It's from way before I figured out all the tricks I've written about since. So you see, I have (had) the same learning curve as everybody.

Example? The design was made shortly after or before textures could be applied to boxes. So I made a box with a wooden texture and then repeated it 200 times to form the wooden "envelope" that forms floor, wall and ceiling.

I hadn't thought of stacking "layers" yet in those days, that's why the pool is at the same level as the rest.
