Click the blocks. Make music.
Be unproductive. Play.
This interactive flash piece is pretty self-explanatory. The program continuously loops through a 16 x 16 tile grid. Every time this loop discovers one of blocks you’ve clicked on, it plays the audio for that piece. The audio pitch for the tiles goes from high to low from top to bottom. And that’s about it.
I have definitely wasted a lot of time playing with this “game” over the years. Still, I’ve never actually tried to recreated the loop for any known melody in it, but I do see any reason that you can’t. Seems like it could be fun to try. Just might have to give that a shot.
