Fibonacci Crossword-style

I love the New York Times Crossword puzzle! I can fly through a Monday but get crushed by Friday. Good times! And I get super-excited when there are circles and themes.

So imagine my joy when I discovered this:

Features of this stellar puzzle:

1. Theme: FIBONACCI SERIES across the middle.

2. Theme-related answers: All the long acrosses (ARTICHOKE, NAUTILUS, INNER EAR, SUNFLOWER) are natural things that display a Golden Spiral based on the golden ratio and Fibonacci series

3. Circled letters: Starting in the lower left corner, the circled letters spell out the words GOLDEN RATIO

4. Golden Spiral: If you draw a curve through the circled letters, it produces a golden spiral. (Yes the proportions are correct!)

5. General Math-Nerd Awesomeness!!
