Boulder-based 10 and 2 Studios, a newly formed video game publisher, said today that it has launched a new, Apple iPhone came called GeoPlay Golf. The iPhone app combines the phone's GPS capability with virtual golf courses, allowing users to swing their phone and walk through a virtual course in real life. The new app allows users to create their own golf courses in such locations as their homes, at the office, or at real golf courses, and take virtual shots and walk through those virtual courses. The GeoPlay Golf app is listed on the Apple App Store for $6.99. 10 and 2 Studios is headed by Matthew Cooke.
