    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 anyone tell me how to compress unicode emoji chars please?
u/cantelope

most of the compression techniques involve converting common (codes 0 - 255) ASCII to unicode, so you have a problem with embedding higher codes or emojis that use multiple higher codes. Here's one approach: https://dwitter.net/d/36129

Thanks. I think I used the same approach you did. I did try having a look at storing the emoji values as hex (with and without the repeating 0x1F) but adding the String.fromCodePoint() added more characters than it saved.
u/cantelope

i mean, the main thing is eval
u/tomxor

I've often place them in separate "uncompressed" variable e.g. s='🌞🔴🌍🪐';eval(unesc... then use s inside the compressed code.

u/tomxor Thank you that worked! I now have 8 planets :) https://www.dwitter.net/d/36151
