You'd probably just have a big pile of splinters.

Sentient splinters.

The best kind!

Seriousanswer: The levers are mimicking the way proteins can conditionally lock, unlock, and fold each other. The parts are amino acids, which can form naturally. IRL they hook electrically through atomic bonding.

Worth noting that the shaking represents heat energy naturally shaking the molecules around. Life doesn't violate thermodynamics because it only works when it is consuming energy, if you stop shaking the box the wood creatures "freeze to death".

I was actually referring to the philosophical question "if God created everything, then who created God".

Thanks for derailing what could've been the most important discussion in philosophy in the 2010s.
