    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.

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

Remixing feels like stealing

u/joeytwiddle

We are very happy for your remix. You gave it back after all!
u/yonatan

Good hackers copy; great hackers steal

This was only running at 20 fps on my phone when I wrote it so results may vary

u/Galaxtone

.... Maybe add t/=3
u/Galaxtone

Looks much better with that
