Wow, that is a good one. If you get a chance there is a youtube video using blue diamonds that does something similar, try looking it up if you are interested
OMG, how? My mind just exploded and splattered all over my netbook. (A little graphic sounding, sorry )
That's no illusion; I just have magic fingers! And I can prove it: Those two boxes are clearly different colors. Yet as my finger passes over, they change color. The only change is my finger. Therefore, it's not the image, but my finger. I am magic. Worship my finger! :eusa_danc
While clever, my mind is too great for your cute optical illusions. I am the master of seeing through it and automatically knew it was the same colour. BWAHAHAHA. Well that and we were shown this illusion in my Sensory and Perception Psychology class...
