Fibonary

Description

Fibonary was inspired by a question from Bram Cohen. Bram asked: "Can we make an exponential puzzle that has a non-integer base". An exponential puzzle is a puzzle where the number of moves to solve grows with a base factor for each piece added. For a binary puzzle, base=2, for a ternary one, base=3. The question immediately reminded of the Fibonacci series (1,1,2,3,5,8,13,...) and the golden ratio (phi=1.618...). Fibonary uses a gear-based adding mechanism. The number of moves for a rotor is the sum of the moves of the two lower neighbour rotors. This results in the Fibonacci series for the number of moves for a rotor, and base=phi.
