"Sight" – short film by Eran May-raz and Daniel Lazo
As good a fictional illustration of far-flung augmented reality as any - the supplementing of what you see by data or visual effect and the potential for the 'gamification' of everyday life. Their take on the 'creep' factor of AR is less about the potential for the de facto alteration of reality, more the availability of your personal information to other individuals (although presumably we'd get a lot more sophisticated about privacy too)
And here's a 3D public digital sculpture tour in Brighton using AR
...and something similar with a dinosaur exhibition at the Royal Ontario Museum, Canada
Digital street art: Interesting less for the practice (woo! we can virtually doodle on buildings! thank you vodka corporation!) and more for the principle of decoration/transformation of the real.
