Something’s not right

I’ve been stumbling around the net again and one stop along the way landed on a page called Optical illusions and Mind Tricks. I’ve always thought these things were cool.

I am not a hamster but when a page has a picture on it like this one has, I know it’s got some interesting, if perhaps a bit weird, stuff on it. That chessboard pic reminds me of a story I read once about a guy who built a house in the shape of a tesseract … a four dimensional equivalent of a cube. Everything was fine until people went inside.

Hmm.. now it’s gonna bug me until I find that story again.
