    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.

Much credit to u/pavel for the comment he left on d/23578, with sample code to illustrate a way of making these collages in a single loop execution.

We calculate a sine and cosine of a small angle delta initially, and thereafter derive them using trig identities using only addition and multiplication
u/rep_movsd

It so happens that C(O) and S(O) are almost exactly 0.8 and 0.6 for some O
u/rep_movsd

I found those by for(N=0.1;N<1;N+=.1) M=(1-N*N)**.5,console.log(N,M)

try this version in a new dweet (acceleration control with up arrow, but I couldn't golf it enough): !t&&(d=[a=v=0],X=Y=99,onkeydown=e=>d[e.keyCode-37]=1,onkeyup=e=>d[e.keyCode-37]=0),x[f='fillRect'](X+=v*C(a+=(d[2]|-d[0])*.1),Y+=v*S(a),s=32,s,x[f](X+C(a)*s+8,Y+S(a)*s+8,9,9,v+=d[1]&v<6?2:v>0?-.1:0))
