Didn’t even have to wait until landed - updated the noise code so the fill functions are now way more efficient when using multiple octaves. The fill_noise8/16 functions (and the fill_raw_* functions) are still in a fair state of flux - but take a look at the header file noise.h to take a look and noise.cpp to see how the raw functions are being used.
FastLED, even faster when flying 425mph at 40k feet.
