    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.

This is the strangest piano i've ever played, but good job!
u/Woodmouth

Also, i found a way to stop it, just press shift. (or any other key with a value too high or low to hear (At least i think that's what happens))

Check the old comments for some simple tunes to play. You'll need to click on the blank canvas for keyboard focus. Hit Space, Shift or Escape for "silence".

Unfortunately I am too far from the party. BTW this dweet runs too quickly. I should have used t/3

Can you arrange the numbers vertically? Feel free to use the special moves!

u/Woodmouth

It's not a space limitation issue, it's a feature!
u/donbright

absolutley brilliant however e.x/e.y dont seem to work in firefox
u/joeytwiddle

Thanks don. I golfed this over a 24 hour period, but could not squeeze a better "valid move" rule in. Remixes welcome!
u/donbright

firefox should adopt e.x and e.y just so your dweet work
u/joeytwiddle

Hehe. Sadly the mouse coords are also problematic in fullscreen, and on mobile.
u/joeytwiddle

Valid moves are -4,-1,+1,+4. I have found a "valid move" test: **2|17)^17|| Will post the remix sometime.
