Well, I did the bounce castle tutorial, and then went "now what else can I do with this?" The result? A rubber room! Scripted door closes automatically, and the floor AND walls have the bounce script. In the corner it has a sculpted white mattress and pillow, with a sitting knees-up pose. You KNOW half the people on here need a padded room!
It's available at my shop in the bahama isles:

Or on SLX:

I have it out on my land for now, if you'd like to come try it out!
