    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.

And another at d/10436, cause I couldn't help myself with the colors
u/Purpzie

Shortened by 10 characters: c.height|= p=m=>(S(Y+t+m*90)+1)*250;for(i=108;i--,Y=(0|i/4)*40;a<b&&x.fillRect(a,Y,b-a,40))x.fillStyle=R(a=p(m=i%4),50,b=p(m+1%4))
u/Purpzie

Oh woops it should be c.height|=p=m=>(S(Y+t+m*90)+1)*250;for(i=108;i--,Y=(0|i/4)*40;a<b&&x.fillRect(a,Y,b-a,40))x.fillStyle=R(a=p(m=i%4),50,b=p(m+1%4))
u/Purpzie

Okay dwitter hates me now, there should be a newline afterc.height|=
u/Purpzie

Honestly there should be an edit button for comments. Forgot to mention I changed the color but it has no effect on code length

Galaxy

u/pavel

300 bodies which individually only interact with an infinite mass at the center
u/pavel

Each body moves around an ellipse, the orbits are accurate. However, the movement speed is a very rough approximation.
u/pavel

Naively drawing an ellipse centers it around one of the focal points, however moving a body on this path slows the body down near this focal point and speeds it up near the other one.
u/pavel

The opposite effect is needed. So this code still moves a body around an ellipse but it re-centers the ellipse on the 'other' focal point.
u/pavel

In polar coordinates the difference between the x and y coordinates is a phase shift of pi/2 ~ 1.6
