Cast Cylinder (錠)

The Cast Cylinder is Vesa Timonen‘s latest contribution to the ever growing series produced by Hanayama. Launched in August 2013 as the 60th puzzle in the series (if my calculations are correct), the Cylinder has a very interesting design and concept. Like many others in the Hanayama collection, the appearance of the Cylinder doesn’t give you any hints as to how it should be solved. Luckily, and unlike Hanayama, they give you a pretty good hint in the description that will sure help you with your task. The theme for this puzzle is “lock”.
The Cylinder is presented in a chrome color and consists of two rings that rotate freely in 360º. Within the rings are three apparently similar pieces that don’t appear to be affected by the rotation of the disks. These pieces don’t move up or down, and the rings can’t be separated either. With a little persistence, however, you’ll see that the pieces can actually be moved.
That’s when the Hanayama hint in the puzzle’s description comes in handy. This is a quote from the actual description: “go about it as if you were cracking open a safe”. That’s also why I mentioned this is unlike Hanayama. They don’t usually give out hints for solving their puzzles, so I was a bit surprised by it. Following this important piece of information I proceeded slowly by rotating one of the disks until I saw something that could indicate I was on the right path. I’m not sure how many complete turns I made with the ring, but it took me a while to finally see some progress.
Eventually, one of the three pieces slid down a bit and I was ecstatic. I wasn’t sure what do next, so I continued and tried to see if one of the other pieces would fall down as well. No luck this time. After some more fiddling I was able to find out that the piece that had slid down could rotate independently from the rings. Again, after doing this for some time, another piece slid down. The two pieces were now side by side with only the third one still in its original position. Some more fiddling and now one of the pieces had fall down even further. The three pieces were now in a cascade, each one lower than the other. From here, the puzzle was a step closer to being solved. It wasn’t long before I could remove the first piece and then the remaining two. A couple of extra steps were needed, but I won’t reveal all of the solution for you.

Now, all I had to do was putting the puzzle back together again. You’d think that’d be easy after seeing the internal mechanism, wouldn’t you? Well, all I can say is that this task is even harder than taking it apart. I can’t remember the order in which the pieces were removed, and the process is anything but straightforward. I tried to follow a solution guide, but that only includes the description of the solving process and doesn’t show which piece is first removed. Note that two of the pieces are identical. So, as of now, the puzzle hasn’t still returned to its former glory.

Solution: If you find yourself stuck you can download the solution here.

Closing Comments:

The Cast Cylinder is quite difficult to solve but, to my surprise, I’m finding it ten times harder to put it back together. This is classified as a difficulty level 4/6, and I agree with it if you’re only taking it apart. However, doing the reverse is as difficult as any of the 6/6 level puzzles. Prepare for some frustration with this one.

The Terrace

This illusion artwork has challenged my perception and logical thinking. It is not surprising why this Terrace illusion has become the most popular illusion artwork of Davids.

About The Terrace

This incredible artwork was David’s first attempt to create a primitive image with non-photographic elements. The illusion of 3D depth in the artwork is fantastic. If you look carefully at the terrace, you will see that it is not physically possible in the real world. You can see that this image was created with a lot of hard work and the design of the terrace is interesting to look at. The terrace was created using computer software and photography. The artist used digital cameras set to 640 x 480 dpi and a computer that had dual processors and a GB of RAM. This very simple method of constructing an image is a favorite of the great Oscar Reutersvärd.

About the Author

David MacDonald does not consider himself an artist, although by the age of eight, he was already taking photographs and starting to use a darkroom. He studied in a liberal school that combined heavy emphasis on the arts, disciplines of advanced mathematics and engineering drawing. He was able to develop diverse abilities which came together naturally in professional photography. He is an Englishman living in Belgium, married to a Viennese and they have two multilingual sons.

David works as a movie camera man and his role is to give life and atmosphere to a director’s vision. He is now in his 48th year of working with film. He is an expert when it comes to interpretative role and the ability to add more dimension of visual interest and mood. Much of his work relies on playing with the light. He has had the good fortune to travel to both developed and remote places of the world because of his work.

He initially discovered a photo editing software that was bundled with a scanner and started to play with it. He was soon exploring other graphics applications. This has now become his passion equaled only by his lifetime passion for Asian and Oriental inspired cooking. His main interest is the creation of photo-realistic Escher like illusions, combining photography and computer generated imagery. A number of these are published in illusion books and can be found on the Web.

Thank you David MacDonald for allowing us to post and share your brilliant artwork. If you wish to see more of his artworks, you can go and visit his website.

Brightness Illusions (Green Square)

It is hard to believe that the top and bottom of the middle squares are actually the same shade. In order for me to see this, I had to use my finger to cover the area on my computer screen where they join. Then it was clear that they are actually the same color. This fascinating optical illusion has become one of my personal favorites.

About the Brightness Illusions (Green Square)

I have learned that this Brightness Illusions artwork is trying to show that the entire concept of an illusion is based on delusion. Through this optical illusion artwork, Beau Lotto is trying to help the viewer to realize that a person can see an illusion whenever the two realities are being entertained simultaneously. Such illusion artwork will help the spectator realize more wonderful things about the brain. The brain is a naturally creative and inquisitive tool that endlessly redefines normality which is essentially relative and historical. This Brightness Illusions will let the viewer realize the influence of color, motion as well as shape in an illusion.

Gaze cautiously at the two big squares in the middle to the image. At first look, one square looks like a light green and the other one is dark green. However, if you look closely, both squares are exactly the same color.

About the Artist

Beau Lotto is founder of Lottolab which is known as a hybrid art studio and science lab. With brilliant, communicating sculpture plus old-fashioned peer-reviewed research, he is able to unravel the secrets of the brain’s visual system. Lotto is enthusiastic about engaging people from all walks of life in research on perception both as subjects and as fellow researchers. The “i,scientist,” in fact has led to the publication of the first ever peer-reviewed scientific paper written by schoolchildren entitled “Blackawton Bees,” on December 2010. All his work endeavors to understand the visual brain as a system defined by its past ecological interactions with the world. In this viewpoint, the brain changed to see what proved useful to see, to continually redefine normality. According to this artist, Illusions are critical windows into the mind.

Thanks Beau Lotto for allowing us to post and share your fascinating optical illusion. If you wish to know more about his artworks then you can go and visit his website.

Arom Pescado Flores

I was fascinated to see this tessellation artwork of Oscars. The gradual transformation of flowers into fish make it hard to pinpoint where the change becomes complete. My eyes were first drawn to the flowers and worked left toward the fish instead of the other way around.

About the Arom Pescado Flores

This Arom Pescado Flores illustration reveals the specialization of Oscar in photo manipulation and character design. I have learned that this illustration has been featured in many talent and art galleries. Moreover, Oscar has created this tessellation by combining and arranging so as to form a mosaic. The fishes which tessellate cover the plane without openings and without overlying.

Street Art for Honda

I was flabbergasted to see this 3D street art. The car and the men in suits are a dramatic touch. The shading makes this piece seem very realistic.

About the Street Art for Honda

This street painting for Honda is a mind bending artwork. I have learned that perception, geometry, lighting, color and movement are all essential to Tracy’s work. She is accessing her intuitive impulses as much as possible. In choosing such an unconventional style in which to communicate with other people through art, Tracy has found a suitable medium to express what’s on her mind and heart. Most of her works are completed within 1 to 3 days.

"Sacred Quetzal", Guatemala

I am always fascinated with 3 dimensional pavement art. I am intrigued by this magnificent work by Eduardo Relero. I can sense movement in his work – it is not just about catching people’s attention. This pavement artwork seems to invite the viewer or passerby to interact.

About the “Sacred Quetzal”, Guatemala

This spectacular 3d artwork by Edward Relero was created using the art of anamorphic illusions. I have learned that anamorphosis is an ancient technique that is still being used today by many artists around the world and it is considered by many individuals as a novelty in art. Anamorphosis is also the 3D art’s heart and soul. It is the projection of objects in such a way that they can have depth which they couldn’t obtain in any other way.

About the Artist

Eduardo Relero is a 3D street artist from Argentina. Eduardo has created optical illusions around the world and that includes his popular giant feet sticking out of gaping holes in the ground. Eduardo started his painting career on the streets of Rome in 1990 and has also made spectacular murals in Germany, France, Spain and America.

3D-painting “ATM”

I find this ATM street art painting striking. Such artwork is compelling and it looks realistic. If I would be given a chance to walk in the street where this 3D art was painted, I would definitely rush to check it out myself. This street art is so tricky and believable.

About the 3D-painting “ATM”

In this ATM 3D street art painting, Qi Xinghua has applied the inverse-perspective method to make far away objects big and close objects small. In this way, a two-dimensional painting transforms into three-dimensional. In most cases, Qi Xinghua seeks the assistance of many trained artists to assist him in creating great works. Many of his creations have taken weeks to complete. In this work of Qi Xinghua, he reveals his secret to his painting: that is breaking people’s customary view of artwork.

About the Artist

Qi Xinghua is China’s first 3D artist to draw the world’s 4th largest Guinness World Record longest 3D stereoscopic paintings. He graduated from the Central Academy of Fine Arts in 2005. He is fully engaged in his 3D drawing career at the Central Academy of Fine Arts. He is recognized as a professional 3D artist who uses roads for his canvas. He created the Guinness World Records largest 3D dimensional painting which was measured by the British Guinness headquarters site.

3D Strassenmalerei in Moskau für Nike

I was completely flabbergasted to see the 3D street paintings of Gregor; his works all seem so realistic. The passersby seem so amused and delighted with his works. His masterpieces are all amazing and I really wish to go to have a picture of myself with his deceiving 3 dimensional pavement artworks. He has the power to bring the viewers to a completely new place.

About the 3D Strassenmalerei in Moskau für Nike

You can watch the video to see the hard work and fervor of Gregor and his team in creating such tricky pavement artworks in 3D. Sometimes, there are real objects which are added in the pavement in order to enhance the illusory effects of his works.

About the Author

Gregor Wosik is an artist from Poland and he loved painting and drawing at a very young age. His talent was noticeable very early and he continually developed it through complimentary art studies and training.

Oskar van Deventer has done it again. Cast Twist is his latest puzzle for Hanayama’s flagship series which makes him one of their biggest partners with 12 designs in his name already. Released last October, the Cast Twist, formerly known as Snake Ball, is a level 4/6 and its theme is “Tangle”.
The puzzle consists of two apparently similar, but distinct parts that start out entangled in each other. Since the two parts appear almost identical, Hanayama chose to coat them in two different colors, silver and gold. The contrast also looks gorgeous and gives the puzzle a shiny and elegant appearance. The size is slightly bigger than the Cast Donuts, with a diameter of 4cm (1.6″).
The goal of the Cast Twist is somewhat straightforward, but still a bit overwhelming due to all these grooves that criss-cross the entire surface of the puzzle. There’s a protrusion in each piece that you’ll be able to use in order to navigate both mazes, so you should pay attention to their position at all times, albeit being difficult at times, because of the tight tolerances between the two pieces.
The first movement that you’ll be able to perform will be to slide the gold piece across the silver one, but you’ll be immediately stopped with almost nowhere to go. The only course of action is to study which path the silver piece should take, and at first your options are limited. As you move further along more paths will open, but so will do many dead-ends. It’s here that the puzzle becomes tricky, and solving it will require a good dose of trial and error, but that alone won’t get you far. You need to figure out how to get to the exit.
As mentioned above, the difficulty level of the puzzle is 4/6, but after spending almost an hour solving it and putting it together, I honestly think this one deserves a higher rating. A 5 would most certainly be a better fit for what you should expect when you try it yourself. Putting it back to its original position won’t be a walk in the park either. It’s equally challenging due to the long path you must take from start to finish.Solution: If you feel your brain “twisted”, you can download the puzzle’s solution here.
Closing Comments:
Oskar’s Cast Twist follows the Hanayama tradition perfectly. A superb design, combined with a fun and challenging solution, and made with high quality materials at a competitive price. It’s no wonder that they sell like hotcakes. Highly recommended, as usual.Availability: You can find the Cast Twist, and all the others in the Hanayama series at PuzzleMaster.
