Best cable elevators for pc and speaker cables?

I made my own from antique glass insulators from power and telephone poles. I built platforms from MDF and cylidrical lengths of oak for the upright supports. I wrapped a layer of Dynamat around the ends of each oak post so that the glass insulators would not vibrate when placed over the oak posts. I use rubber bands to secure the cables onto the insulators. They look cool and do their job. Searching for and collecting the various size, shapes, and colors was fun too. Of course the blue insulators sound best!
