If I converted this to grayscale the illusion of motion would disappear, right? RIGHT??

I didn't get the positioning of the now-not-running guy at the end exactly the same in all frames, but hey.

Still illusive.

I wonder if you get the same effect if the guy at the end isn't running and it's in greyscale?

For me the big one just didn't work as well. The two with the rulers blew my mind.

Now I am going to have to try this if I have graph paper somewhere. I wonder if it would still work if you drew another line along the crease in the graph paper.

Had some graph paper so tried it. The illusion only works if you close one eye, and keep the paper evenly lit. Well lit with straight lines and a dark crease line appears either behind or on the cube’s surface but doesn’t effect the illusion of the cube snapping into place. Shading each side would probably enhance it.

I normally keep one of these guys hanging around near my computer.


But I can't find mine right now - I think I gave it to one of my sister's grandchildren when they last visited. I'll have to print and fold up a new one.

Here are the instructions and downloads if you want to make some - just print a single sheet on a color printer, cut out around the outline and fold into shape - the instructions are on the parts of the paper you cut away - very simple and kids enjoy making them - a bit of sticky tape or glue-stick on the tabs and base holds them together more securely, but you can manage without.
