    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.

Original uncompressed code: z=500;x.fillRect(0,0,z,z);x.fillRect(z+100,0,z*4,z/3);x.fillRect(z+100,z/1.5,z*4,z/3);x.fillRect(0,z+100,z*4,z/3);x.font="500px a";x.fillText("◤",z-100,z+z);

I used u/metamero 's compressor: https://www.dwitter.net/d/11852
u/13thptr

Hi :) your code can be shortened so that it fits into 140c without compression : z=500;x[s="fillRect"](0,0,z,z);x[s](600,0,z*4,z/3);x[s](600,z/1.5,z*4,z/3);x[s](0,600,z*4,z/3);x.font="500px'";x.fillText("◤",400,z+z)

You need to write a blog about this particular technique
u/taupelink

i'd like to, but it would take time (i'm a super slow writer) and it's honestly not a priority at the moment. I can at least say this: Part of how I get four vertical bands is having Y range from less than -1 to greater than 1 (in this case, -2 to 2). Multiplying or dividing by Y then has four effects: stretch or compress, do or do not reverse sign
u/rep_movsd

A one page breakdown would be nice, or perhaps I'll write one
u/taupelink

ah ok...like a line-by-line explanation? that's doable...i'll write something up next weekend!
