I’m using just the rainbow HSV->RGB conversion part of FastLED here, against my own SPI output routine (which, I’ll admit, isn’t great). It’s amazing how much more vibrant the colours look using this algorithm even when not cycling through hue values.
For comparison, pictured in the background is my map of Black Rock City 2014, which uses a fixed-point spectrum algorithm I found on the ARM-mbed forum.

Here’s something I whipped up for the New Orleans decompression. The build quality is just passable but it worked for the night.
I don’t think JST SM connectors are very good at passing a 40MHz signal across them, however.
The APA102 strip here is being controlled by a BeagleBone Black, which is speaking SPI. It’s pretty easy to get going, but if you want a quick start you can find the code I used here: https://github.com/tullo-x86/spitrance

Looks great! And it’s always cool to hear of someone using parts of FastLED in conjunction with other libraries and their own code. There’s a lot in there and we’re happy when people (re)mix and match.
Also, thanks for the note about colors! It’s something we’ve put a lot of time into, and it’s nice to hear a multi-project experienced lightbender say that they noticed the difference.
Do you also have closer-up video of the piece in the background there? Looks slick…
Your pattern there has also given me an idea, hmm…

Sure do, here you go: http://youtu.be/tl5YtmH4h54
You’ll notice that the yellows in that one aren’t nearly as defined 
I ran out of memory on that chip though (I had to inline like a million things in order to not run out of stack space) so I’m not sure I’d be able to get FastLED integrated and have it still work. I might try anyway because I’d love to have it look as nice as the jacket.
Also, the prototype was missing an LED as I fried the first one in the strip by getting it a little too hot while soldering. The framed version has 24 LEDs which all work
Cool layout and design.
What MCU were you using when you ran out of space?
Cute… and cheap! (And low on space…as you pointed out!)
