More optical illusions

Every day I get up and wish for some fine fine optical illusions. Mainly I want a killer headache so I can legitimately call in sick to work but sometimes I just wanna look at some cool stuff. So enter this Optical Illusions blog. It showcases the best and most interesting optical illusions from around the world. The problem I've found with most of these sites is that the content is usually old and boring. This website seems to be updated regularly and actually contains lots of stuff I've never seen before. Cool, eh?
