    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.

Fantastic!

well, it is not like Flappy Bird anymore. it is just two squares at the same position all the time instead of tubes at random heights
u/username

and I feel like it is constructed in a way that makes any improvements very hard
u/KilledByAPixel

it's a demake of a demake. some really good ideas though, i've already used them to chip off a few more bites from my version

Wanted to make a 3d lattice with perspective
u/joeytwiddle

Didn't you already achieve that in d/13728 ?
u/pavel

Different method of generating a 3d lattice that rotates. Why is rotation so simple in this form?

f defines Y and Z and rotates them by angle t. Really efficient.
