    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.

Somewhat ambiguous because of implicit orthographic projection

(first dweet :D)

add |0 after i/w for a more solid look
u/lionleaf

Nice! Glad to see you make a first dweet :D
u/jylikangas

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))
u/13thptr

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

If you change this bit too use t it's like Saturn uses its ring as a hula hoop: 540+m*C(n+p*t)

u/Purpzie

This is absolutely beautiful.
u/tomxor

Thanks for all the kind comments :) for those interested: the key is in the parity bit p=i&1 this allowed me to combine two different but similar functions by multiplying parts in an out on each iteration. You should be able to pull the two apart into something more intelligible.

@tomxor are you on Twitter as @tomxor by any chance?

I am not, nor am I on any other social network... unless you consider Github one :P but a different pseudonym..
