    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.

per donbright's suggestion... :D

u/cantelope

mouse Y position controls resolution
u/donbright

lol surely there is more we can do
u/tapgiles

Cool! Some of the lines seem thicker, and some seem fainter. Is there an overdrawing issue, perhaps?

If you set canvas.width to client.width, you can remove the bit that fixes the mouse position. This one only works at the default width (not fullscreen) because I had to hard-code the canvas width to make room for the fade effect. Nesting stroke inside beginPath saved 1 crucial byte. :)

u/cantelope

canvas.clientWidth rather
u/cantelope

i will give 3 gold stars to anyone who can fix the initial "Y is not defined" error :D
u/magna

Since your dweet doesn't use trig, we can hijack C and S as declared variables: https://www.dwitter.net/d/2429
u/magna

Can save another 2 bytes by: R(Y,X,fillRect(0,0,w,w),.2,beginPath(stroke()),moveTo(X,Y))

A triforce.

u/cantelope

I'd love to see someone else's attempt at this. Feel like I did it the hard way :s
u/sigveseb

Maybe there is a Unicode triangle you can use?
u/cantelope

@sigveseb, I would worry about subtle variations in display size/position across browsers. but that's a great idea.
u/donbright

im thinking maybe some kind of sierpinski style but it wont be easy
