New, from Domicile and the Gentlemen Bastards, something for the Tomb Raiders among us. This 20m x 20m, 30-prim ruined temple has cold running water, several fallen columns, and no way out. Things aren't looking good for your roleplay group, unless you can fathom out a way to climb up through that hole in the roof that you fell in through!
The light beam affords local lighting for nighttime RP: the perfect accompaniment to the slow, inexorable drip-drip of water down those damp walls that hold you trapped. Oh, and the whole shebang is fully-modifiable, but don't let your GM see you edit a wall so you can sneak out ;-)

Decent and Cheap!
This chamber looks pretty good for it's age, but is poorly designed. After i modified it's only about 7-8 land impact instead of 30 :) The creator for some reason used 2 prims for each wall, so unlink one prim from each wall and stretch remaining prim to fit, then scale texture 2.0 horizontal repeats, offset 0.5 to center. Same with the floor and ceiling and water. Also we can set links to physics shape none nowadays so no need to have the water and lightbeam using a script to make the flexible...after a bit of work you'll have the same looking chamber with 1/3 the land impact :)
