I’m afraid no one would define any of my attempts so far as pretty except to call them pretty bad! That’s actually a great idea though, I could probably reduce the money sink a bit by trying to them some of my projects into art work. Thanks for sharing that idea!
There is serious work happening on building perpetual motion machines of the third kind (one that moves forever but does not produce energy). But to contribute to that work takes years of serious study. It's probably a good idea to do that study in a formal setting to avoid fooling yourself into thinking you understand when you don't.
