Mine was a kitchen. Tile floor, sink, stove, counters, refrigerator. I had two non-working animations, one of the water turning on and off, the other of the stove turning on and off. I even had these jars that were supposed to be transparent, but the only transparent tile was the top left one. Auto Masked, of course. Awful Isometric perspective, no variation of color. I stopped once I realized that all I could do is run across the top of the tiles because of the no transparent auto mask.

Great fun, I'll see if I still have it laying around somewhere and post a picture.
