I love Richard Wiseman’s Blog. Every week he posts puzzles and optical illusions. Some weeks I can solve the puzzles in seconds, other weeks have me thinking about them all weekend. It’s all good stuff that messes with your brain, and makes you think. I while back he twittered a really cool site. I ment to blog about it last week, but kinda forgot. Go check it out, it’s pretty self-explanatory.
