Today's Question of the Day:

What's the prettiest rectangle?
Any questions about Fibonacci number decomposition and Fibonacci Nim? The former is how you win at the latter!
Fibonacci Numbers and Nature:

- dandelions (Here's a scanned dandelion)
- Spirals in daisies:
- Similar spirals appear in artichokes, pineapples, etc.
