*Okay, it's really cute and smart, how can I not.
*I have decided that most projection-mapping isn't "really Augmented Reality," as it doesn't fit the Ronald Azuma definition of being reactive to users in real-time. Projection-mapping is better understood as projected cinema with 3-D registration.
*However, "8-Bit Invader" LOOKS JUST LIKE it is being reactive in real-time, so maybe that moves it into some weird new formal AR taxonomy, like, say, "Fake Augmented Reality."
