There was this wireframe rollercoaster screensaver that used to be available for Windows 3.1. Seems like I got it off AOL or Prodigy, or maybe even GEnie. It would only work on systems that had a math coprocessor (it worked on my -DX, but not my friend's -SX). I found that it you synced it up to this specific MIDI it would start and finish at the same time as the song, but for the life of me I can't remember what the song was. It was amazingly primitive by modern standards, but blew my mind in the early 90s. I must have stared at that rollercoaster for hours.
