RunAmuk writes "Wired is reporting about being able to "Point and click your mobile phone at a poster in London movie theaters this July and you'll be able to directly access the movie's Web page." While there are many practical uses for this technology, like in museums as the article suggests." I'd like to use it at video rental places and CD stores to get product reviews.
If you're using a computer at CMU (or one of Telerama's wireless hotspots in Pittsburgh), you can find out when the next bus comes near you at bus.maya.com. Perhaps it's not as glamorous as streaming Quicktime movies to your phone, but it's probably more useful ;-)
That said, I hope someone solves the location-based services infrastructure problem. The bus hack depends on mapping IP addresses to lat/lons, which is incredibly brittle and evil.
