    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.

XD. now the background color and the text color aren't so Stalin...
u/katkip

and it's not centered
u/joeytwiddle

This is centered on Mac. I tried px, em and vw but all have the same problem: smaller on Linux, larger on Mac.
u/f8f82804

163 char with centering: with(x)((f=a=>font=a+'in ☭')(1),f(1800/measureText(s='☭𝔇𝔴𝔦𝔱𝔱𝔢𝔯☭').width)),(lineWidth=44+99/t-9*t)>9&&(strokeText(s,60,650),strokeStyle=hsl(${t*56} 99%50%)

u/joeytwiddle

Very clever mini dithers! How about dithering a sphere?
u/f8f82804

A sphere is a good idea! I'm still trying to work on spatial coherence though; see my earlier Floyd-Steinberg demo to get an idea of what's possible with 2d error diffusion. This dweet is a start at using a mask instead of diffusing errors.
