Seven years is an impressive age for any online world, when many virtual worlds and MMORPG's fall by the wayside well before that age.
This week, Second Life reached that age and celebrated with its annual birthday sims, events and more.
The party was run over just a single week, compared to previous years two, but as always, it is themed.
This year's theme was "Unexpected Collaborations," which leaves a lot to the imagination.
