    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.

that is good but we lose the curve which is the only thing holding together the composition

great attempt! not sure it is possible to get smaller without cutting something. in this case the X%4 part is necessary to make the trees varying heights
u/FireFly

"boring" -1, distribute the ?: across args in the fillRect: x.fillRect(t?X-r*i/8:i*8,t?600+(r*8&3?i-h:h-i):r*600,t?i/4:h,t?2:r). Or more depending on what artistic tradeoffs you're okay with, e.g. just always setting height to r isn't terrible

Night city from the sea #cityscape

Hello. I want to use this code in my future game as generator of the part of the background. Also I would try to modify it slightly so generation would be partially random and big "skyscrapers" will have more details (2-color grid representing windows)

Prime fun 3 / 3 - when X is less than Y, then X modulo Y gives X, so we see the normal vertical prime stripes, white shows X is a prime. not sure about the rest, there seems to be a large white line around the line where X equals Y, #math #primes

Prime fun 1 / 3 - This is the standard X&Y (binary AND) Sierpinski triangle picture but only where X & Y is a prime number. perhaps revealing a relationship between primes and binary AND #math #primes

(note white = X&Y is prime, black = X&Y is composite)
