    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.

Interesting hack! Basically, this is c.width|="Right-to-left Override unicode character goes here";for(i=9;i--;)x.fillRect(400+i*100+S(t)*300,400,50,200)

u/iverjo exactly! It took me a little while to find a place to put the character and still have valid js

WOAH. How do you even copy and paste the special character?
