If, instead of increasing its size by 100%, we increase it by a smaller

Heh, I have a talk about it. The limit is the golden cut,
1.6180339887498948482... The proof is fun. Anything larger prevents you
from reusing previously used space. -- Andrei
I was going to ask for the proof, but I first went to refresh my memory
a little about the golden ratio, at which point the proof became
somewhat trivial.
