That was actually very interesting... especially for someone like me who _will_ attempt to break every brick or clear every balloon before they re-appear. The two black-and-white patterns with shifting patterns were incredibly addictive puzzles (to me, anyway). After my mouse marred the cleanliness, I just _had_ to get it all to one color again, somehow.
Several of those could be turned into actually fun mini-games. The ones with the bricks that revealed a further, larger layer of bricks underneath would be insane if it had several more increasingly small/distant layers, a time limit, and a counter.
