Code: pestis
Additional code: TomCat
Techniques: glitched kaleidoscopic IFSs, raymarching, shading based on the number of steps, a*(1+b*dist^2) glow.
The video mode setup and bankswitching loop are based on code by TomCat, from Kacifántos creatures in a chaotic dream.
The shadertoy prototype is here.
Requires enough video memory for 1024 x 768 x 32bpp video mode; dosbox does not support this. Use dosbox-x, with:
vmemsize = 4
