There are several representations of London in virtual worlds, but this week Designing Worlds takes you on a tour of the original: the London sims in Second Life. We meet two of the partners behind this extremely popular region and visit a resident's home, as well as seeing the sights, from Piccadilly to Big Ben and much more. We also visit the place where Saffia, Elrik and the founder of the London sims, Debs Regent, first met in real life.
