    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.

I'd try wider, supposedly biological brains are very shallow, but massively parallel.

I think these would do better if they showed up all at once. I tried to muck around but your q logic is hard to compress for(k=99,m=t?0:5e4;X=S(m),Y=S(m*m--);x.fillRect(k*q*X,630-i-q/Y,q*q*m/9e5,i/Y))i=m%k,x.fillStyle=R(q=k/(1+S(k*X)),q=q%9*i,q-Y*k,k*Y*Y/q)

https://www.dwitter.net/d/23557 so with some space for setting up other buffer view, it speeds things up when treating rgba Uint8Clamped Array as single 32bit value

wondering if we could store that buffer somwhere to do truly iterative fractal stuff

Rising from curved space

u/Xen

very nicely
u/Toby

Lovely! How can you use r in the loop header without first defining it (done in the loop body)?
u/danny@hille.dk

Creative use of geme mechanics :-) The for loop has 3 sections separated with semicolons, first is for initializing: this is runs once before the loop starts, second is exit conditions: runs for every iteration before the "loop scope", third is for incrementation: this part actually first run after the loop scope. EX: for(i=9;i--;console.log(j))j=i*2 i is initalized to 9 i is decremented if i equals 0 (any number in js is evaluated to true except 0 wich is false) the loop exist then the j is set to two times i in "loop scope" finally j is printet to the console
