You can get some PVC pipe of a nice, wide gauge. Then slice it in thirds, 120 degrees each section. There are PVC paints you can use to make these whichever color is available. You might need to rough the surface of the PVC, first. If you want them plain white, there are ways of removing the colorful print. Use the round, ooh-ah PVC sections instead of the flat, painted-aluminum (or plastic) trays. The round surfaces should reflect the light below in a more eye-pleasing way. Still suspended from the ceiling, though.
You could buy a lot of smaller gauge PVC and run the cables through that. Do yourself a favor and cut the sections in half, and hinge them on the side away from the wall so you could still open them up section by section if you had to. Attach the PVC to the walls with washers and bolts at stud points. Close up the hinges and latch with whatever. You could paint it bronze and it's be kooky, steampunk style stuff yeah.
You could do real steampunk style, and buy metal pipe instead of PVC. You could have this cockamamie maze of pipes running up and down the walls, over the chairs and desks, and arriving at lamp posts (actually lit by flickering LEDs, not actual gas! Hah! Haha!) which the office workers discreetly plug their computers and other devices into.
You could get simple tin foil (food grade) and wrap the cables up in that. I have no idea how this will affect their performance in terms of temperature. But they'll be shiny.
You could get some plastic mesh and spray paint it silvery, double the edges and run your support wires through the doubled up holes. The mesh should theoretically be able to support a bunch of wires (maybe triple fold those edges). The cables would show but hey, they're colorful.
You could just support the bundled up cables themselves "naked" to the eye. It would be a bitch to get at the cables and take any down without taking them all down, but there they'd be. A person looking up could see how the network is "shaped". It would be like a magic trick.
You could support all of the cables on a bunch of really, really tall hat racks with allll kinds of crazy hats hanging from them, along with all of these network cables. People would wonder if they could have a hat, purchase a hat, or add their own hat to an empty prong. You could just deny them the satisfaction all day, and come across as WAAAAY more smugly superior than they.
Get a bunch of fake Christmas trees and throw out all the stupid false needles, just leaving behind the weird wire skeletons. Put a bunch of them together in a giant matrix of wiry voodoo. Thread your cables through this, along with strands of blinking LED "holiday lights". Put the giant borg in a really obtrusive location so everybody will question THAT, and nobody will care about how unappealing or inconvenient it is to have the cables snaking to and from this thing to various other locations.
You could build a glass ceiling and snake the wires around like crazy and make it all topsy turvy, artsy fartsy with your artistic talent glass ceiling existing purely for art's sake. Clients and other visitors could be invited to throw little peastones at it, to give it character.
