    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)

A triforce.

u/cantelope

I'd love to see someone else's attempt at this. Feel like I did it the hard way :s
u/sigveseb

Maybe there is a Unicode triangle you can use?
u/cantelope

@sigveseb, I would worry about subtle variations in display size/position across browsers. but that's a great idea.
u/donbright

im thinking maybe some kind of sierpinski style but it wont be easy

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.
