I don't think you're going to be able to replace a whole art package this way - even if it's capable of that level of detail I expect it'll strobe like crazy - but replacing lamps? Yeah, I can see that. Fake inserts or tactically-empty areas of art that you then beam on top of. The trick would be not to go overboard with it, so every time you use it for something over than an insert, it never stops feeling special. Have they tried projecting on top of printed art, and seeing how clearly it turns out?
