I struck on the idea back in 2012 to make a little javascript application that would take images (PNGs with alpha transparency) and layer them to create new compositions. I was thrilled with the results (I like to make things that surprise me), and I’ve been tinkering with the concept on and off since.

I’m now experimenting, in the current version, with mixing raster and vector images, working with presets and palettes, and generating subtle variations of the generated composites.
