    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 tried to render a circle,but got this texture instead

u/Joachim

Nice work! Have a look at this if you want a circle. Change M to change the render speed --> for(i=2e3;i--;x.fillRect(i,t*M,1,M))M=600,A=i-960,B=t*M-540,x.fillStyle=hsl(${S((A*A+B*B)/9999)*99},69%,69%)

cool effect - but at the same time scary to think that this is what my incurable cancer could look like, which unfortunately is slowly but surely spreading and seems to be gaining the upper hand.

Really cool
u/dabl03

It looks pretty good, how do you compile the code?
u/shandriy

I used CapJS (capjs.3d2k.com) to compress it.
