The Encke Virtual University Collaboration brought educators from around the world to an island in Second Life to listen to some presentations from experts in the field, embark on a series of field trips but most importantly to collaborate in teams around a number of topics including bots, communities of practice and gamification. Like the comet Encke, the Encke Virtual University Collaboration had a long tail, with a number of workshops and events, and collaborations developing over the following months.
