    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.

just have your y movement be a function of x -> w=c.width=1920;N=70;for(j=3e3;j--;x.fillRect(X+4*(X/120*Y/100)+90,Y+X*.1*S(X/N-7*t)+55,9,9))X=(j%N)*15,Y=((j/N)^0)*15 x.fillRect(N,50,9,w)
u/danny@hille.dk

for(j=w=c.width|=N=60;j--;x.fillRect(X+4*(X*Y/8e3)+90,Y+X*.1*S(X/N-7*t)+55,9,9))X=j%N*15,Y=j/N*20;x.fillRect(N,50,9,w)

good thing dwitter only allows 140 bytes, or someone would probably have done something like this:

no fuckin clue how i got this in 81 characters
u/Qwitter

if you send a single pixel across the screen at this resolution (70) like fillRect(X+t,,1,1,1) you can see how the canvas has a smoothing effect by slowly pouring the alpha = 255 value between the pixels
