There's also my favorite: live-editing a VR environment. https://www.youtube.com/watch?v=db-7J5OaSag
I think a lot of people who are just starting out get deterred when the only thing they end up with after a week of effort is some hard-to-see changes happening on the filesystem or in some file.
But I must add that anything which gets new coders excited is a good thing!
Closing the feedback loop between typing and seeing a cool result is one of the best ways to get people excited about coding. If 3D or AR helps with that, it's definitely a good thing :)
