Using specialised software it is possible to project any image or video, of any shape or size, onto any object that is covered by a projector. The key point being, only the object has video on, nothing else.

Not only that but you can play multiple pieces of media, on multiple objects. 

If it’s a physical thing, it can be projection mapped. Whether this be something small, like a tea cup, all the way up to something really big, like a building or tree.
