optical illusions

Optical illusions from eChalk

For me the first one is the most extraordinary; I had to take a screen capture and move bits of the image around to believe that it was actually true. Illusion 3 also seriously broke my brane.

if you focus on the fact that the one that looks lighter is in a shadow - and then look at the two of them together - you can tell they're the same color. just compare the lighter one IN the shadow with one out of the shadow. that should do the trick.

at least, it does for me.
