maze in a garage

For the past couple of years, I've been setting up my display in the garage. Basically, I had a bunch of props scattered around with no real structure or theme. TOT's would just walk in, check out the scenery, get their candy, and leave. I found a site where a guy created a structure out of pipe in his garage that essentially created 5 small rooms. I'm going to try this, but I can't find the site to give the guy proper credit (or ask his advice).

Has anyone else done this? The structure itself is pretty simple. What I want to do is pump fog through the frame and drill holes in the pipe so that the fog will seep out along the floor. Can a standard fogger do this? I was thinking of maybe having a 'Y' coupler at the fogger and using a fan to help push the fog.
