LOL Jan. One thing that counts as a Fibonacci sequence is to take any number IN the sequence, as there are only set numbers allowed, and use them randomly. So if you memorize a few of the smaller ones or like pick 3, you know, it doesn't have to keep increasing.
My friend says when the numbers get really large it creates THE most pleasing pattern to the eye, but I don't think it would work for knitting. Maybe if it were stitch by stitch? Stitch by stitch would be cute in crochet spirals, maybe.
