Reset, by roBurky. I ran into this a few months back, but it didn’t occur to me to put it here until I was reminded. It’s essentially a videogame version of a music video. It lasts as long as its song does and matches its action to what happens in the music. I enjoy it quite a lot, and I hope you’ll take the four minutes or so to give it a try (it’s Windows-only, though). One note: try not to read too much on the download page until you’ve gone through once.
