Quite possibly the smallest WebGL demo effect. Micro Nova clocks under 512bytes and shows supernova-like blasting colors.
How did this happen ?
This started as a discussion with Daeken, discoverer of the PNG bootstraping technique, about the feasibility of a 512b WebGL intro. However with ~160 bytes for the bootstraping itself, the PNG approach was not the right one to hit the 512 bytes mark. The only way was some good old sweat, hand minification and hashing of verbose method names.
Of course there has been many variants of the fragment shader before settling for Micro Nova. Some bringing us as far down as 507 bytes but the visuals were slightly less intereting.
Here is the breakdown of the various parts:
52 bytes of HTML + CSS
134 bytes of GLSL ( 44 and 105 for the vertex and fragment shader respectively. 15 bytes are shared between both shaders. )
