    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.

Set l=9 for a double whopper and modify 213 to customise your ingredients.

This was a not-so-impressive #tribute to this burger advert: https://vimeo.com/178939743 and here is a similar Smores advert: https://twitter.com/MachinePix/status/994279… But isn't is a shame we waste so much human effort and ingenuity on advertising (and silly dweets), instead of solving the world's problems? #capitalism #cognitivebias

I had hoped to round the edges of the bun. Alas. #food
