This is a coffee table I built from a salvaged Textronix 7704A oscilloscope mainframe I pulled from a dumpster. A sheet of glass on top and a wooden frame complete the table. (I added the frame because I kept bumping my shin on the invisible glass!)

Though I had hopes of resurrecting the scope (originally a 5-figure piece of quality test equipment), it had sat in the rain for a little too long. The PSU in particular had about 14 different output voltages, some of them high, and was completely fried. So I removed some shielding to expose the beautiful insides and made it into a bitchin' coffee table.
