I’ve seen one or two musical items inspired by video games. There was Andrea Vadrucci who drums along to Mario Bros. Just found a violinist who plays the mario game music and sound effects in real time along to a game as its being played. I’ve seen opera in virtual worlds.
But I think the animation I’ve just found is quite excellent. It’s 80’s video games animated out of everyday objects. I particularly like the pacman near the end. Very well done. Its called Game Over and you can see it here on YouTube.
