Sure, you could rearrange these cool-looking Tangram shelves. But I bet you a dollar you won't.
You actually think with a kid rolling around on the floor, you'll have enough free time to precision-rehang seven oddly shaped shelves purely for your own amusement? Why, that's almost as crazy as thinking you can patent on a design. That's at least 200 years old. Good luck with that.

Man, how freakin cool are those? So does patented mean you can't make them yourself, or just that you can't sell them...?
