As a young guy I listened a lot to the PRO tracker module "mod.galaxy" by Firefox. I wanted to make a demo to it but I lacked the commitment and the skills to do it. Now, a few years later I have discovered shader programming at shadertoy.com and wanted to recreate the demo I had in my head. Obviously today's computers are way beyond the old Amiga but I tried to capture the feeling and some of the tropes from classic Amiga demos.
