Actually I'm reorganizing mine, the idea is to build a 3-mode desk, one part is an on-wheel structure, just two legs and an upper part, the upper part sustain the monitor and two 5-6 rack unit side-by-side standard 19" places plus a plane to keep wired keyboard and mouse etc there.

A second detachable part is a keyboard stand to be used both in standing mode and in sit-down mode.

The third part is the sit-down part: a treadmill with a long chair on top, to allow stationary standing mode, slow march mode, sit-down one all in the same furniture.

So far I've just made few prototypes with scrap wood though...
