If you're in Second Life, you should check out Svarga [SLUrl]. It's an exotic jungle island with pathways, towers, musical instruments, isolation room, fountains, temple compound, secret underground chamber, lookout posts, a second island, and even its own ecosystem (birds, bees, flowers, plants, trees, weather). There are lots of details that are easily missed the first time through. When you get there, be sure to take the guided tour by sitting on the hovering tour chair.
Svarga is my favorite place in Second Life. Unfortunately it may not be around for much longer.
