"不可能立体工作アート トリックミュージアム"
Impossible 3D Craft Art Trick Museum Series
These are a series of optical illusion papercraft kit which I found in Japan. There's a total of 6 kits in this series (with rough translations) :
I - 左が左右、右が上下の壁 (Left is left and right, right is up and down)
II - 重力を無視する屋根 (Gravity defying Roof)
III - 重力を無視する坂1 (Gravity defying slopes 1)
IV - 上が一直線の4本柱 (Four columns in a straight line above.)
V - 4面通り抜け窓 (Four-pane windows)
VI - 重力を無視する坂2 (Gravity defying slopes 2) a.k.a magnet like slopes
As shown above I own series I, IV and V. However I only did a full video of the first 2 (you can see how illusion V works at the start of IV)
Illusion I
Illusion IV
Most of the footage I got are in the videos as I did not take pictures of the contents whilst recording.
These impossible objects papercraft were created by Kokichi Sugihara, which some of these objects can be printed from his official website.
