For this build, I wanted something that reminded me of an old science fiction mad scientist laboratory wall.  I started with a rough sketch on paper

 I wouldnt be able to fit an entire 4ftx8ft sheet of plywood in my car to transport this, so i opted to cut it into quarters and went from there.

I used various pieces from the hardware store, such as copper ties and valves.  i also spray painted PVC pipes a nice metallic colour, and the PVC connectors got a rose gold paint.

I added some steampunked lights i made out of brass fittings and then sprayed painted the whole thing with chrome

Unfortunately, i forgot to take pictures of the finished prop.
