A rather big Fib.

So since motris is trying to get KenKen under control (i.e. only reasonably popular, and with plenty of deserving puzzles), I thought I'd contribute. This one is themed with Fibonacci numbers arranged in a spiral pattern. Not as pretty as it could be, but provides plenty of variety.

A note: in this operationless KenKen, the 1 in the corner is either - or / and must start with the largest number first.
