An SL blogger named Alf Eaton recently used the Mappa Novus service to generate giant, 13 meg size images of the Second Life grid, which has far exceeded the viewer's dynamic map. Get them at this link. Above, Osprey Therian's mark-up of the map, showing the area of SL that existed when she joined in 2004. Great way of getting a sense of the world's growth. Hat tip: Shiny Life.
