This is awesome! This makes designing augmented reality a lot more accessible to a lot more people - so a lot more artists can enhance their portfolios and make a lot of apps more interesting by using this to add AR features! The examples in the video are pretty cool, they really bring the textbook to life (with a literal beating heart) and it seems that there's a lot of room for innovation with this technology.
I think board games can have clever uses of AR, since the board itself should be able to stay put, but maybe it can score points in a more interesting way with an AR app.
