Romanesco

Part of a Romanesco Cauliflower. Note how the main florets are composed of mini florets arranged in a Fibonacci spiral and that these mini florets are in turn composed of micro florets, again arranged in a Fibonacci spiral, which themselves are composed of.......... - isn't nature wonderful!

 

It reminds me of the old bit of doggerel:-

 

If dogs have fleas

Do fleas have fleas

Which on their backs do bite'em

And do those fleas

Have lesser fleas

And so, ad infinitum?
