If you haven't experienced a Microsoft hololens yet, you must give it a try! It's absolutely fantastic technology. Glasses equipped with kinect, gyros and camera(s) superimpose "holograms" over you natural surroundings. Of course they're not real holograms but they put objects into reality and it looks like a hologram (e.g. a shark swimming in your living room or the solar system hovering over a table). It's full 3D and it's like the object was standing there in your room. You can look at it from all possible angles and walk around it. Really amazing stuff which will revolutionize our society like the smart phone did.
Of course it could also superimpose something over your own body.. let's say boobs or a horse dick... or the back of a horse or centaur. That'd be fun and the dream of changing into the animal of your dreams could become closer somehow - even without drugs, hypnosis or costumes. Only the tactile feedback is missing.
The cool thing is that objects placed into the room by you will become also visible to other people carrying the glasses and vice versa. So you could look like a centaur, dog, hind, etc. to others too. Cosplay will get a whole new meaning!!! Until we get holodecks, this is the technology I'm betting on. The glasses only have to become available in the consumer market - with a bit a wider view angle and not so expensive.
And somebody needs to write these nasty apps...
