Something noteworthy for this community: The Spout Sprites feature has extended Milkdrop beyond its original design. Sprites have always been a feature built into Milkdrop, but we tweaked it so that a Spout video stream can playback within a Sprite. This enables all sorts of wild possibilities such as mixing together different preset visuals, nesting the visuals within the actual drawing process, importing external Spout video streams, and creating feedback loops. Here is a tutorial I created which explores some of these possibilities.

We also set up a Reddit community dedicated to NestDrop.
