Currently I'm studying Graphic Design, and recently we were given the Tangram excercise. I'm shore I've done something like this back in School many years ago. Basically all you have to do is rearrange the shapes and make shore they don't overlap. There are stacks of combination's to be made. I came up with two, something that looked like a Computer character, with ear's and a tie, and below, which is more of an abstract form. When the other one comes back I'm shore to post it up.
