Fibonatree
I don’t get the Poincaré one?
He worked on topology, where every shape is analogous to any other shape as long as you do not tear, cut, fold. So a disk would have been funnier.
After New Year all kook the same. Only this one maybe still usefull

The guide lines on Fibonacci bother me.
Merry Christmaths!
