Elektronenmultiplizierer

Straight 1:1 port of Elektronenmultiplizierer from Demoscene Passivist (http://copypastaresearch.tumblr.com/) using WebGL. The intro renders a fullscreen billboard using a single fragment shader. The shader encapsulates basically two different routines: A sphere-tracing based raymarcher for a single fractal formula and a bitmap orbit trap julia+mandelbrot fractal renderer. Additionally an inline-processing analog-distortion filter is applied to all rendered fragments to make the overall look more interesting.
