Good lord I am clueless, to me the pic looks like a sort of wavy looking tree with some sort of Halloween backlit melting face engraved into it. Sorry to not be more help I'm actually not even confident in not calling it some sort of weird mech clone....
How old is it? Where did you get it (geographical area)? And yes, do you want to replace it with something similar or just identify it?
That is... Please, summon the power of your verbal and mental powers of description and if there is anything you can add DO SO, LOL and also (believe me I am pictorially challenged too, all my pics look like I've run them through the randomizer filter) maybe there's like, some ah better lit, more detailed pics you can provide, now that you can post them?
