Fun on Friday #15: New Year Health Check

After the excesses of the Christmas and a hard week back at work, I felt some sort of neurological test was in order.

Have a go at the Spiral pinwheel illusion.

What do you think? Have you been damaged by too much over-indulgence?

If the pinwheel illusion amused you, there are other good illusions at the eChalk site.

I especially like the Mona Lisa one.

What's your favourite? Do you know of any other good optical illusion sites on the web?

Haha, they're good David. I particularly liked Colour Perception 2.

My daughter simply refused to believe the chess board colour perception one. She is convinced that there's some sort of electronic trickery going on. :-)
