    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.

Remix of u/Jezza 's cool idea, but using the Gregory-Leibniz Series, just to show how it converges much more slowly.

donbright: Hah! In the original game, https://play.google.com/store/apps/details?i… , you have to tap the black tiles as fast as you can, and you can't tap the white area. In this dweet, I replaced it with keyboard strokes: you have to hit 0, 1, 2 or 3 depending on the position of the bottommost black tile (0 for the first column, 1 for the second, and so forth). Unfortunately I couldn't add any game logic or score to it.

omg thank you this is great. actually reminds me of DONKEY.BAS by Bill Gates

I've never heard of donkey.bas - and I've been using computers since the good ol' Apple ][ !! Shit, now I'll have to implement donkey.bas on dwitter! :D
