thanks man, and yes. I had already 2 or 3 years experience with the different scriptable elements and partial differential equations in Milkdrop when they introduced the shader editors in the 2007 Winamp5.5 release. There were several original shader presets by Ryan Geiss and i started to edit them and that's how i learned it in the beginning. A good bunch of my presets has also made it into the official download since then too, but i have literally thousands more on my hard drives. I'm still looking into the Milkdrop forum every once in a while but i haven't been much active there since i graduated from university. Have you published something too? What's your handle? In 2010 I started with my first OpenGL clone of the shader pipeline in a Processing sketch and then came WebGL... and I must have gained enough attention with that to get invited to talk about the stuff i do at the FMX2013 this year. The thing is, my current position as a database backend programmer has pretty much nothing to do with my hobby. Thanks for heads up, it's much appreciated! That's surely something i need to fix asap, but soon i will also be the father of _two_ daughters.
