    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.

The target

u/lewdev

Neat, it looks like craters within craters. The target was hit on the same spot by bombs of smaller and smaller blast radiuses.

[vn-07] P in G, P on G, Ping Pong - by va!n

u/vain

This dweet is a riddle in which you have to guess the meaning of the graphic/image. The solution to the riddle is a "P in a G" and a "P on a G". This results in "PinG PonG". Kind of stupid; but also kind of funny too. (Unfortunately, the image puzzle doesn't seem to be displayed correctly on a smartphone)

amazing!

Director's cut changes that I want to do in retrospect: 1) remove Q and replace its definition by D*=D>0 so multiplying by D is the same as multiplying by Q then D, and 2) replace j/5 by j/10 and j=1e3 by j=2e3 so the patterns on the blocks before blowing up dissapear. Also 3) M=_ instead of M=()
