A googol, ten raised to the power 100, is larger than the number of elementary particles in the universe so the fact that someone can construct a mechanical device that requires the use of the term in its description is really impressive.

It's not that hard to construct computational examples that can exceed a googol of combinations or permutations but physical mechanisms are a whole other thing.

Despite the stunning magnitude of the googol, there is an even bigger number, the googolplex, which is ten raised to the googol power; in math notation 10^(10^100). If you want a real shop challenge, design a mechanism that demonstrates a googolplex as this one does a googol. Good luck.
