I can't even figure out what to call something like that, even Google Images doesn't know. I'm curious how long it will take for someone to solve this one.

I'm interested in a little bit of background info aswell... haven't got a clue as to what this puzzle is...

The puzzle has been solved in 35 minutes! Winning transaction here:

The solution to the puzzle was a QR code, solving the puzzle works as follows. Each grid of four squares has a number, this number indicates the amount of black squares in that 2x2 grid. You can use this information to color squares black and solve the puzzle.

Very nice try though! Smart to do it on your computer, or you would have had trouble scanning it.

Damnit! I thought about QR code but dismissed it. Did notice the 3 patterns in the corners.

Haha I would have never been able to solve this, but awesome puzzle. Wonder how long it took someone once they figured it out to color in all the boxes and then scan it on there phone once they figured it out. Also, wonder how many people were coloring boxes and solved the puzzle only to figure out it had already been solved.
