edge_burst effect improvemnet propose

Not an actual issue, if you consider it inappropriate and if this is not the right place, be free to close it immediately, I don't mind.

As always: Thanks for great software!

I much like edge_burst ARTI-FX effect, maybe because it perfectly fits to one my lamp.
I improved it for my self this way:

t1 = triangle(time(.1)) -> t1 = triangle(time(0.3 - speedSlider / 1000)) (so I can set the speed)
f = index / ledCount -> f = index / intensitySlider (so I can set the wideness, not the best solution, but it is working)
s = 1 -> s = custom1Slider / 255 (so I can set saturation, almost like changing color palette, not exactly)

Full code I'm using:

program edge_burst {

  function renderFrame() {
    t1 = triangle(time(0.3 - speedSlider / 1000))
  }

  function renderLed(index) {
    f = index / intensitySlider
    edge = clamp(triangle(f) + t1 * 4 - 2, 0, 1)
    v = triangle(edge)
    h = edge * edge - .2
    s = custom1Slider / 255
    leds[index] = hsv(h * 255, s * 255, v * 255)
  }
}

I believe, with your programming skills, you can improve it even more. Be free to implement above change if you like it.

Thanks.
