In the 6th episode of FastLED basics, we look at the noise functions. These can be somewhat difficult to understand and there isn't really any documentation to speak of. Noise provides a 'smooth randomness' that allows plenty of interestinglooking patterns with only small amounts of code if you know how to use it!

CORRECTION: Around 16:15, I should have said that the last parameter in nblend is the amount of the second array to blend with the first from 0 (0%) 255 (100%). I got mixed up with the fadeToBlackBy function above it.
