I was working on this one before my absence. It is VRML right now, but all the interior work will be done with AC3D. The bathroom, the kitchen, the bed area, shelves. etc. It is on display at
http://h1.ripway.com/mykeld if you want to explore it in 3d. As I get each of the 8 levels done, will update this post. Got a good portion of the next level done too but there is no image of it at this time.
