Hah, it fits! awesome

#crt #fractal
u/magna

It's monochrome, unfortunately. I couldn't find a quick way to add color (i.e. adjust the intensity based on R/G/B cells.)
u/tomxor

I can sort of fudge the colour with some kind of mod3 to selectively modulate the intensity in lum: (2+i%3)*n*10%50 duno how to fit it though.
u/magna

Nice! I used the dweet compressor (d/9207) to compress it: d/10843
