I was surprised superconductivity wasn't mentioned. The new part here isn't the "perpetual motion" it's the complexity of the pattern. I guess in some highly abstract sense it's like exciting a more complex resonance mode in a bounded system. The simplest mode gives you a simple output, more complex modes give you more complex outputs.
