Nice work!, I actually did try a solution with fillRect - but it totally kills my laptop, runs kinda ok on my phone though (I get around 11fps with this dweet on my laptop, 28 on my phone)
u/danny@hille.dk

btw nice trick with ++e, i haven't seen that before, I'll put it on my toolbelt right away :-)
u/KilledByAPixel

Yep, had to make some sacrifices for speed. You can do w=127 and get a pretty good fps!
u/danny@hille.dk

this is my aptempt: reduced the resolution to get at bit more performance: c.width=w=127;for(m=w*w;m--;x.fillRect(m%w,m/w,1,(Y*(o=(3-(4-5*e+S(t))**.5)/(e+1))*w+t*w&w^X*o*w&w)/w))e=(X=1-4*m/w/w)*X+(Y=-2+4*(m%w)/w)*Y
u/danny@hille.dk

with the ++e trick its only 137 bytes :-)
u/danny@hille.dk

Sorry i hadnt seen you wrote back, yep i did 127, (any pow(2)-1 will work for the xor pattern)

u/magna

Yay! Not that it would greatly help bring it down to 140, but: (i>>5)*8 could be i>>5<<3 or even i>>2&-4
u/magna

I want to try rendering in one pass, like a shader, picking the right colour based on a bump map (either procedural, or maybe from a suitable emoji).
u/magna

I had this failed attempt back in 2018: for(i=3e4;i--;x.fillRect((C=i%213)*9,(T=i/213|0)*9,9,9))x.fillStyle=R((C%21+1)**T%255,T**(C%21+1)%255) for(i=9;i--;)x.drawImage(c,X=400+i*100,400,50,200,X-9,400,50,200)
u/KilledByAPixel

still trying to figure out why the other one had artifacts and this one seems not to, maybe something to do with randomizing the background you mentioned
