    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

That is so cool! Took me a second, but the star really pops!
u/rodrigo.siqueira

Wow I can see a ⭐
u/tomxor

Haha, nice star

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

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).

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)

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

i'll just believe you all since i'm blind in one eye lol

Thank you. 🖼️

I like. One of my hobbies is ceramics and this pattern recalls certain oriental decoration techniques, very interesting
u/donbright
