    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.

Circuit Diagram

u/tomxor

Nice! most convincing xor sampling #circuit pattern i've seen, lots of ball grid arrays
u/ntsutae

(i-t)^(i+t) is great.
u/rodrigo.siqueira

Change ^ to | and you will see falling Sierpinsky triangles! I mean: (i-t)|(i+t)
u/ntsutae

Yes, I've already tried "|","&". The triangles appeared without the use of recursive call. Dwitter told me bit operation skills. Thank you.
