Heads up that the Diorama Room M stuff is up for pre-order in various places
Here's Amiami:
http://www.amiami.com/top/detail/detail?gcode=FIGURE-040802These contain a set of acrylic boards that slide together (no glue required, they're held together with pegs) and stickers for the walls and floor. They also sell the boards, wall stickers, and floor stickers separately so you can mix and match floor/wall textures or just paint on your own backgrounds.
Pic is an example of one being after being populated with stuff from the previous thread
