Now I Just Need a Lego Feynman to Crack It

I love Lego creations that are not just sculpture, but are mechanical devices; and I’m not talking about those programmable Lego robot things. They are ok, I guess. I’m talking about mechanical objects based on simple Lego pieces to create gears, wedges, levers, and all those other fun Newtonian work devices. Like this Lego combination safe (created by Merijn van Wouden).


Now, I just need a Lego Feynman to crack the combination and access my nuclear lego secrets.
