    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.

Oh the nostalgia! #basic #prompt

I've realized I could have encoded the bitmap data a lot more efficiently. Will try to shave some chars to add translucency to the font and add a blinking cursor.

Hah, it fits! awesome

u/magna

It's monochrome, unfortunately. I couldn't find a quick way to add color (i.e. adjust the intensity based on R/G/B cells.)
u/tomxor

I can sort of fudge the colour with some kind of mod3 to selectively modulate the intensity in lum: (2+i%3)*n*10%50 duno how to fit it though.
u/magna

Nice! I used the dweet compressor (d/9207) to compress it: d/10843
