Design Blocks/16 Cubes: Block Puzzle

It's a simple idea—no instruction manual required. But you'll be astounded seeing amazing designs take shape before your eyes as you move the blocks around in countless ways. Believe it or not, there are more than 2.8 trillion possible arrangements just with each block in the same position relative to the next! If you start changing the order of the blocks, rotating them, or (gasp!) stacking them, the possibilities must number in the gazillions! Clearly you could spend the rest of your life arranging and rearranging the blocks, although we don't really recommend you do that. We do, however, recommend unleashing your creativity with Design Blocks whenever the urge strikes. What superfabulous pattern will you make next?
