There is a lot here! Multi-leveled world with plenty of interesting visuals. It feels much like any science museum would...you walk around to various rooms/exhibits that have some sort of hands on or interactive display that has something to do with space or science in general. Plus there are artifacts from start trek that you can explore.
Had to mention this one. I was greatly impressed with this location. It starts you off in a room that is black and white. Gives you a sense that its old. There are artifacts lying around that belong to someone. The room looks trashed and there are propaganda posters all around. It really gives you a sense of place and time. Then you can explore what looks like a German town. The town has been ransacked by the nazis. You can go inside the buildings and looks through peoples belonging, including journals. Its very eye opening and I imagine that anyone that visits would learn something.
When I first landed in SL, someone gave me this link and I went straight there. It is small surf island where you can actually go surfing. I havnt been able to try it yet because the boards coast big bucks!, and you can buy swimming trunks, shades, suntan lotions, etc. There are even different wave breaks. There is a small break for slow easy rides and a larger wave for faster rides. Someone said that If you are lucky you might find a board laying around on the beach that you can use.
