mouse over the blocks to spin them

This is embarassingly simple, but kinda fun to play with. The red block (there will always be one, randomly placed) adds a tiny bit of design interest. One of the things I am interested in playing around with is trying to teach a program how to create a Mondrian-ish or Mark Rothko-ish design... not just how to make a simple composition made of blocks, but how to discern (or at least guess at) what balances a composition. (File under machine learning and wishful thinking)
