I love stuff like this... first of all actually getting to the sim itself is a bit of fun.. there are a couple of manholes to wriggle through, one takes you to a little floating island and the other takes you to the sim where it is perpetually raining, dark and oh so glorious.
It's a mysterious place and great for SL photography nuts... really worth an explore, get your camera out, see what you can find and celebrate a masterpiece
