There Is No Green Dot!

I love visual illusions, and this one is really cool (via The Neurophile). I'd never seen it before.

As usual, looking at one visual illusion led to looking at more, and now I've got a headache. Once, I ran an experiment using after effects, and spent hours and hours looking at the stimulus as I was trying to perfect the Matlab code for the experiment. I had a headache for like three weeks.

Oh, and thank you Chicago and Vancouver folks for the restaurant recommendations. Does anyone in either of those cities drink, though? And Austin people, where are you? I know there are good restaurants and bars in that city, and I'm sure that someone reading this knows of at least one of them.
