January Journal: Fibonacci interests

jjhunter was the first to give me a prompt and offered the really clever suggestion of Take a fibonacci sequence of your DW profile interests... and tell us something about each corresponding interest... not commonly known. Which gives me a lovely random grab-bag of a post, and also reminds me that I haven't really updated my interests list in most of a decade, but never mind.

( Fibonacci numbers always make me think of hypothetical reproducing bunnies )

[January Journal masterlist; there's still quite a few spaces so do feel free to add some more prompts even if you didn't get to it in December! Or indeed to make a second request if you're already in the list.]
