    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.

This starts with a dual structure for 2 possible values of "r" (random 0 or 1) and then a triple structure appears when r is changed to 3 possible values ( 0 or 1 or 2) #tree

uBlock Origin custom filter to hide compressed dweets

u/pavel

As a bonus it hides itself because you no longer need it... heh
u/f8f82804

d/16645
u/joeytwiddle

To avoid (some) false-positives, you could get slightly stricter with e.g. :contains(eval):contains(unescape)
u/joeytwiddle

For beta.dwitter.net replace .dweet-wrapper with .card
