levitating books

Here's my project for the week, I made some levitating books for my wall.

I really like how they came out, it looks sweet. Your eye kind of refuses to understand it at first.

EDIT: I've had a couple people ask me where I got these, if they were from Ikea or something. No, I actually made them. I got books from Goodwill, hollowed them out, screwed angle brackets inside them, and attached them to my wall. Only the bottom book is the "shelf" (and thus ruined). The others are just loose books from my collection.
