Pretty but not Functional
The CEDIA awards for the Best Dressed 
Wiring Installations were referenced recently by Slashdot. They depict some really beautiful wiring installations, but they are horribly un-maintainable.
My work-study job in college involved wiring up the dorms for ethernet. It was a lot of fun and I learned a lot about wiring. Amongst them was the fact that these systems are constantly changing.
As network installations are made in new locations, or as faults are found in the networking infrastructure, the physical wires or terminations need to be changed. If everything is neatly tied down and bundled with such care, replacing a single cable involves unbundling the entire installation.
A useful installation needs to be orderly, but still support a rapid exchange of cabling. Just a couple of velcro straps will do much more nicely than a zip-tie for each and every port in the patch panel!
