ConQwest "big game". ConQwest is a promotional event in 10 cities for Qwest Wireless. It is a high-stakes treasure hunt in the urban jungle. Five teams of high-school students, armed with Qwest Wireless phonecams, race through the city searching for treasure in the form of images called semacodes. Semacodes are the 2-D barcodes that can be captured by phonecam and decoded into digital information (as already mentioned at Mobility@lse last year). The technology, pioneered by Semacode, Inc, was further refined by Dennis Crowley (of Dodgeball.com), and Kamida. Take a look the Area/Code web page, the ConQwest 2005 web page, and also some event photos.
