Total depth was 9" maybe?
(1/60)meters to inches = 0.656168 inches
Distance between LED centers = 2.625 + 0.25 = 2.875, or 4.38 LEDs across



Global fade-in function? This will get around some timing issues with timeMult & speed control


Ideas
-----
* Sky + clouds, go through a whole day... sunrise colors, sunset?
* Like the scan phosphors, but less residue. And lots of small phosphors rising up, instead of lateral movement? Maybe some cool color opportunities there, like have larger (but darker) phosphors in the background. Lava lamp pace.
* Night sky animation redo? Just twinkle individual ponits?
* Very slow waves expand from darkness, then dither away into solid deep colors, then back to black. Like a very viscous fluid. 
* Slow jelly climbers way down, make them short & basketball-sized, and instead of climbing, they can just warble in & out of each side
* Slow down stripes of many colors, and fix some of the palettes. might be OK? Use a greater number of stripes, and wider?
* STripesOfManyColors: Maybe non-uniform texture? Clusters descending & rising?
* Clock?
* Color cycling on fractal noise
* Falling leaves



Ideas -- too fast
-----------------
* Water fills up
* Perspective 3D road
* Tiles ascending
* Circuit board scrolling
* Rotating stripes on the Y plane? Hmm
* Contrasting diagonal motion (vertigo! wooo)
* wavelets hee hee



// NEED CUSTOM PALETTES:
- JellyClimbers
- Night Sky
- Long Gradient
- Arches


// Generic color palettes: all blues, purples, greens, etc


>> GridRain

>> FiresOfManyColors

>> SwarmsInTheCorners
- fix the drawRGBLine method, better antialiasing around the line caps?
- particles can be too desaturated / bright? add color?
- Use less swarms, use only visible surfaces, yay performance
- overall speed is OK?
- weird problem on exit(), swarms started flying fast? Just remove the custom exit motion?

>> ScanPhosphorAnim

>> ConveyorBeltsAnim

>> NightSkyAnim

>> StripeTraffic
- Better palettes somehow?
- Change the density of the stripes
- Divergent traffic, no need for the sides to mimic each other

>> Jelly climbers
- Colors?
- Change BG color?
- More up & down motion?

>> Arches of Power
- can this be salvaged?
- palette

>> WhiteWaves
- Arch tops are greyscale when special palettes are on

>> ScanPhosphor

>> LongGradient
- Experiment with other shapes & contours of light
