Spectrum Cube is a Quartz Composer composition based on the spectrum cube from Édouard Puginier. You see your album art jumping to the music, with a nice introduction at the beginning of every song. It shows the strength and the weakness of the iterator. The cuttings of the album art are made "by hand" because if the iterator does them the results are not cached and so it would drop from 60 fps to 6fps
