    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 is cool!

WOW!

Side note this effect is going to look best on apple devices and probably isn't going to work well on android or windows. Apple gives me at least a couple pixels of windshield on most or all of the vehicles, which extend nicely in to the third dimension. Google and MS's cartoon outline are going to break the illusion completely I'll bet

Mouse over the screen; a red square follows the mouse.

u/wclang

Note, you'll get an error message until you mouse over the screen.
u/wclang

There's a magic number, 3.3, that keeps the square under the mouse. This doesn't work in full-screen mode (the square is offset from the mouse).
u/wclang

I should mention I learned that mouse events are accessible from FireFly #1629. (I had to figure out what was going on in that dweet, so I could get X and Y off of the mouse.)
