Very cool...
Though I was surprised at the one that said say the color the word was written in and not the word itself.
Supposedly that illusion exists because one side of the brain processes the word while the other processes the color thus there is a conflict.
I had no problem at all saying the color the word was written in out loud without hesitation. Well - a bit of hesitation in the middle but none elsewhere.
Wonder if that means I don't have a dominant side of my brain. That might explain why I am equally comfortable working with statistics and taking pictures with a camera.
The spinning pinwheel and creepy crawly skin worked exactly as advertised. The moving gears one though barely moved and didn't make me feel sick even after staring at them for minutes.
