    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.

harmonic wave equation (in javascript notation y=(x,y)=>A*S(2*Math.PI*(t/T-x/λ))) - move mouse to change wave length and amplitude (period is fixed at T=1 for simplicity)

u/marc8 I guess we had the same idea. However, my intention was to show a harmonic wave equation using d/14535 and then I just remixed that
u/username

actually, d/14535 does not do that. I did not post the dweet I had originally drafted. it used the above equation (in my very first comment) in code and that is exactly like that

I tried making the values for the deviation between pi and the replay speed as accurate as possible to prevent desynchronization (pi / 3.66 = .8583586585218014)
u/username

you can save a lot of bytes by playing at roughly pi sped up (d/14496)
