After a bit of fiddling round with some viewport setting code (or lack of viewport setting code..), got my intermediate RT working, and got a simple texture working. I’m wanting to use this to render patterns to, and have the vortex render it back with some kind of kaleidoscope effect. No effect yet, but the framework is there. I think it’s time to start working on some mechanics, instead of being drawn into the graphics too much. I’ve still got procedural music to do yet >_<

kaleidoscope...without the mirrors.
