    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.

amazing remix, as always :D
u/cantelope

was wondering where you've been.. i shudder to think what you can make within 1kb. feel free to remix my work on codegolf.tk if you like.
u/pavel

Thanks man! I was on vacation in New Zealand for a month with just my phone. I'll check out codegolf.tk, I do like optimizing down to 140.

#Unicode code point ⇄ char converter : left is code point in decimal 🔃 right is character : useful for copying individual combining marks #tool

u/metamero

use ctrl-a then ctrl-c to copy the combining mark on its textarea. then you can it use by pasting after the character you want to modify. once a character is modified, often you can't select just the combining mark anymore, so this little dweet can help to choose and select diacritical and other combining marks. you can try all unicode range e.g. 휂 55042 U+D702. zoom in ;)
u/metamero

focus and edit any field then click out of it
