VIDEO Sugiharas Impossible RooftopIf you’re an old time fan of Mighty Optical Illusions blog you’re already familiar with all kinds of #impossible objects. We’ve featured hundreds of them over the course of seven years, however, after seeing creations of mathematician and professor Kokichi Sugihara, I will think before I use the word impossible going forward.

Sugihara’s award-winning creations often combine 2D-looking 3D structures with dynamic elements (rolling balls in this case) to toy with our perception of scale, dimension, and linear perspective. One I’m about to show you was presented few days ago at the European Conference on Visual Perception in Sardinia, Italy. For those of you who find this video familiar, you’re right – We already featured Sugihara’s creations in one of our earlier articles.

Sometimes the program turned these objects into real objects, and that’s how I discovered that some impossible objects are not really impossible. They can actually be built as solids in three-dimensional space.” – Sugihara

    beautiful three dimentional “solution” of a two dimentional impossibility. Ai’nt perception great!!

  7. sophie says:

    absolutely amazing! I was trying to work it out for ages i even had to pause the video to think of the possibilities. When they rotated it I felt so stupid! Why didn’t I think of that?!

  8. Danisnotonfire says:

    Omg that was absolutely amazing!!!
    i thought that there were magnets or something used and when they rotated it i had to rewind and watch it all over again to see if that had actually hapened!!!!

    I might build an object like that…

    It’s a strange sensation when this site gives daily proof that we can’t completely trust ours brains to tell what is true or not on initial observation.

    All I can say is that that roof would be no good in the rain!

  12. John says:

    Its just a magnet and magnetic marbles

  13. mclois says:

    The most impressive thing is that it still tricks me, even after the video rotated back and I already ‘know’ what is going on.

  14. Ivo says:

    It’s not really perfect, shadows are a tell. Balls are casting shadow on a bright side of the roof, which is impossible. But with little gray it could be perfect.

    think its a belter.am just in the throes of building an ames window so do like the o/i.as im,m retired gives me something to occupy the grey matter.by the waqy ivo,just enjoy,we can all see how it works !

  16. ciccio says:

    They were actually 3d-looking 2d structures (not vice versa).

  17. Milton says:

    Interesting. My head is still spinning.

  18. Wakener says:

    Thank you, Ivo; I was about to say the same thing. I figured it out before I even saw the video, and said, “They need to paint the sides of the roof different shades.”

    • Renee says:

      I knew something when I saw the shadow on the light side of the roof…should have figured it out, but I didn’t. Refused to believe the logical over the optical. Maybe next time,…maybe not! LOL

    this was is outstanding!

  21. ME says:

    wow that was amazing! I didn’t even know what was going on

    I found a wonderful series of creating a fabulous illusion and wondered how I could get the photos to you. I have no url because they were sent to me by a family member so I saved them.
