    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.

rotating square

u/Ghoust

does anyone know a better way of doing this?
u/danny@hille.dk

I'm not sure it's better, but this another way: c.width+=0; x.translate(960,540); x.rotate(t); x.fillRect(-250,-250,500,500)
u/KilledByAPixel

for(c.width|=i=4;i--;x.fill())x.arc(960,540,500,a=i*11+t,a)
u/rodrigo.siqueira

I like this 3D rotation: x.fillRect(700,300,400,400) ; c.style="transform:rotate3d(1,5,2,"+t*2+"rad)"

It should be noted that the negative width or height resets to the default (300x150) but zero is retained.
