Todd Holoubek's NonDesk is an experiment of how much one can subtract from what we think of as a traditional computer desk, while maintaining the core elements of usability required to get "work done". It's aesthetic is industrial, but the footprint is extremely minimal, thanks to a central pole design which suspends the monitor, keyboard and tablet for stand up or seated use.
Using aluminum pipe and speed rail fittings a pole is placed between the floor and ceiling. The pole is held in place with compression. At the top end of the pole is a piece of threaded rod that allows the pole to expand and hold itself in place. The monitor, keyboard and tablet are suspended from the pole using ergonomic supports for computer equipment.
We'd actually like to see this concept further; it's a great start but could be further explored using a small case PC like the Mac mini or the ASUS Eee PC, eliminating some of the extraneous wires/cables snaking below. And ideally all the wiring and cables would hide within the pole and only pop out behind a flat panel display. But as a concept, Todd's setup is an inspiring example of functional minimalism compared to the wasteland of clutter most of us battle near and around our computers.
