    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.

If you change the "🐳" character to "X", they will run faster. If you change it to number "1", they will run on their knees. If you change it to "6", they will run jumping.
u/KilledByAPixel

Thank you all, this is one of my best. :)
u/Polyducks

What trick are you using here? Is the code minified into escape codes?
u/Polyducks

Omg killedbyapixel! I saw your byte battle last night!
u/Toby

this is beautiful quite apart from the dweetness!
u/KilledByAPixel

thank you! you can replace eval with throw to see the code.
