Happy Fibonacci Day - celebrated every 11/23 because the date itself 1, 1, 2, 3 represents the beginning of the famous Fibonacci sequence. (Okay, technically, it starts with zero.)
One of the most fascinating properties of the Fibonacci sequence is its relationship to the Golden Ratio roughly 1.618). As you go higher up the sequence, if you divide a Fibonacci number by the one immediately before it, the result gets closer and closer to the Golden Ratio.
Lilies often have 3 petals, buttercups 5, chicory 21, and daisies can have 34, 55, or 89. The spirals on a sunflower or a pinecone and inside a Nautilus shell typically follow Fibonacci numbers.
A Fibonacci poem (often called a Fib) is a short form of poetry that uses the Fibonacci sequence to determine the number of syllables in each line.
Here's a sample by Gregory K. Pincus (no title - that's a zero?)

Poetic,
Spiraling mixture:
Math plus poetry yields the Fib.
