Fibonacci

This is a photo of a photo. It is some sort of insect egg on a leaf. You can see it in St Andrews Square Edinburgh as part of the science festival, the little pockets are for the beastie to breathe and they follow the Fibonacci sequence which I learned from seeing this photo. It is something like add the last two digits together to get the next one: 0,1,1,2,3,5,8,13, etc.
