    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.

can in theory generate almost any dweet, but will practically never draw a single pixel

There are 128**140 == 1.0218702384817765e+295 possible Dweets :) If one dweet eval takes 1ns (being very kind) that will take 128**140 / 3.154e+16 == 3.24e+278 years to permute (that's thirty-two duononagintillion four hundred unnonagintillion)

I suppose I more useful estimate would be the probability of an evaluateable string string... No idea how though.

Trinitron #crt #scanline #fractal

u/tomxor

Finally resorted to UTF8. This is a reasonably accurate slow motion aperture grille scanline animation... Although if run very slow you will see it's not simulating 3 electron beams. t=fps (scanline) w=width (subpixels) the later must be a multiple of 3 and 5. Use X, Y and floored F to plugin your own fractal!

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.
