    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.

ZZT. Bonus points for making the background black and the face white, to look like the original.

Damn! Worked on Chrome on my Android, but not Chrome on my Mac (weird). The building isn't visible. #emoji
u/joeytwiddle

256px is the highest you can go on Mac Chrome, 324px on Mac Firefox. To work around, scale down the canvas.
u/BirdsTweetCodersDweet

Works fine on Chrome on Linux
