I'm in the middle of designing an oracle at the moment. I'd agree with what people have said here that you can make an oracle with pretty much anything, but on the other hand I'd stress that the oracle is only as good as the meanings you attach to the "props" you're using.
IE you can use Playmobil gubbins, shells, different types of bird as you like, but say you do a casting, and get the Playmobil kerosene lamp, you need to have thought in advance what the meaning of that is, or else you're thinking "Um, great, what next?"
Not to suggest you should pulverise all spontaneity out of it by analysing and analysing imagery till you disappear up your own proverbial, but just like Tarot I suppose, the more comfortable you've got with the symbolism of each thingymabob beforehand, the richer the things that come to mind when you draw it in a reading.
