In my late teens, I worked at a telecom in desktop support and ended up on a multi-day project installing hardware at a switch site in Cleveland. They'd taken on a new director who was furious at the condition of the cabling/cable management[1]. I remember a piece of paper with a sliced black zip-tie taped to it and the words "FIRED" scrawled in big letters. Teams of two men were working throughout the site.
They were ripping out/replacing a huge number of runs. During the week, a group was working on a bundle of what looked like thousand Ethernet cables coming from the ceiling, all labeled, starting out as a perfectly laced 3x2 ft rectangle through the channel in the ceiling and then falling into a spaghetti pile extending most of the floor of the large room.
By the time I left, that channel was nearly done, the wires broke off at 40 or so points in different bundles ranging in size, but most were inches thick/wide, wires joined the bundle at various points in the metal channel causing the wire bundle that went to the floor, below, to be only a little smaller than the one coming in. Every curve of every bundle was visibly the same radius.
After seeing what could be done, I decided to learn how to do it. :)
