Funny I was just going through some things this evening and found a speaker wall mounting kit I bought several years ago for mounting bookshelf speakers on the wall. It looks something that could be adapted to mounting a euro on the wall and looking on ebay, they appear to be less expensive. Would have to do some custom work to attach the skull to it but that's just another option. I think they usually are rated by how much weight they can hold so you'd need to find one heavy duty enough for the piece in question.
