Software-based abstract visualizers first appeared along with early MP3 music players as a sort of nifty thing to watch along with listening to your MP3s. One of the most powerful and innovative of these was a plugin for Winamp known as MilkDrop, which was developed by a Nullsoft (and later NVIDIA) employee named Ryan Geiss. The plugin was extensible by using visualization equation scripts (also known as "presets").
