Somewhat ambiguous because of implicit … by 13thptr

function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)
x.fillRect(400+i*100+S(t)*300,400,50,200) // draw 50x200 rects

    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.

Welcome! Very nice 1st Dweet! Golfed to 131b -> c.width=w=400; with(x)getImageData(fillText(font="17px Hello",0,19),0,w,j=99).data.map((e,i)=>e&&fillRect(j*C(i%w/63-t)+j,i/w,3,3))

thanks for the nice comments ! u/jylikangas cool tricks but it seems like inlining fillText in getImageData won't work in FF :(
