Looks like some kind of blue light filter mode?

@foone @eniko

That is a very handy trick to know.
Presumably you could increase the randomness by using a different, randomly chosen (from the set of numbers that work for the given size) feedback number for each overall loop? Or even just start on something other than 1? (unless starting on 1 is necessary?)

It's also the best explanation of the bit operators I've seen too, I can never get the hang of those.

@foone @eniko

Thinking about this, is there a reason you wouldn't just run the loop once, save the order in an array and iterate over that?
Are the bit operations faster than retrieving something from an array would be?
