Ask Slashdot: Recommendations For Beautiful Network Cable Trays?

First time accepted submitter murpht2 writes "My company prides itself on an office environment that follows a modern design aesthetic: open floor plan, bold colors on the walls, cool lamps in the corners. We're now engaged in a significant upgrade to our IT systems and we have a clash: the IT team leader wants to run network cable in trays hanging from the ceiling so all the client computers have high-speed access to the new servers; the guy in charge of the office design wants to keep things looking clean and the cable trays don't fit the bill. We're in a building made entirely of bricks and concrete, so we lack some of the between-the-wall spaces that are used in other settings. Any suggestions for beautiful cable trays or other alternatives?"
