We had a pile of glass TV base plates at work. The TVs were used as monitors to display information and were all wall mounted, so I was given the glass base plates. There was a circular mounting pattern of 6 holes already in the plates, with a small metal plate just around the holes. I thought these would make a great set of matching shelves with some washers, nuts, and 4' threaded rods. This is the end result. It has an interesting look with the 6 rods through the middle. I am thinking about attaching a permanent lamp or something on the top to hide the washers and nuts at the very top.
