Nice looking demos, I hope to some day manage to get results close to what you have.

I started playing around with GLSL recently and the closest I have come to describing working with it is that it is like creating poetry using math. Getting started was much easier than I expected, getting good results is so far as hard as expected

Thank you for the kind words, and you're on point with "poetry using math".

I started 2-3 months ago or so doing this stuff, so don't be too intimidated to start. Especially with the two articles (Red Alp and this one), it should make it more accessible, hopefully :)
