This experiment may not make a lot of sense. I was playing around with the idea of a movable interface whose pieces blend together, and this is a sample I made. As it is, it doesn't do much, but it could become something cool. I guess I just like playing around with it, but maybe that's because I'm a dork.

Click on one of the blocks in the middle to pick it up, and then click again to drop it. The 'plus' in the lower right adds another block, and the other three icons allow you to switch the shape of the blocks. [requires Flash 5]
