This is just awesome. I love the simplicity See if you can figure them all out. Once you get them, it’s like “ahhh…duh”. Pretty cool idea. I wish I knew who created this (I’ll try to look around a bit more) because I would love to see more of them I’ll bet someone out there will be able to tell me the awesome artist behind this.
UPDATE: I think I found the guy, but his site is in Spanish and I’m not sure if he’s actually the artist.
