Qualcomm uploaded a compilation of the best entries that were submitted to their developer challenge.
Back in October 2010 Qualcomm released their SDK and they announced a developer challenge with cash prices up to 200000$. In November they released their SDK as a plugin for Unity, which made creating awesome games with it very easy, if you already had experience with Unity.
Since the devkit is still in beta, this is the first glimpse you can get on the future Augmented Reality games on Android.
All games that are shown run on a Nexus One or similar handset and when the Qualcomm Ar Kit is officially released, a lot more Android handsets will be supported.
