In year 2007 we conducted a research project in Virtual World Second Life. We purchased a private Island in the Virtual World. We constructed around 6 major buildings and undertook several projects using Linden Script. The three main projects are listed below.
1) Collaborative UML Diagrams in 3D world
2) Virtual World Exam System
3) Scrum based project management in 3D world.
It was a great learning experience
