A few months ago I realized that despite setting alerts reminding me to get up from my desk periodically, I just wasn’t doing it. Having read several articles about standing desks, treadmill desks, etc. I set up an approximation of one using boxes on my desk and on top of my CPU case:
DYI standing desk using boxes
This worked fairly well, except that when I wanted to switch from standing to sitting or vice versa it was a pain moving the monitor off/onto the box, etc. I noticed a co-worker downstairs had obtained a WorkFit-S Stand-Sit Desk Attachment, and had my boss arrange to get me one as well. Here it is in the standing and sitting positions:

The WorkFit-S costs about $400 (note that the writing shelf above the keyboard tray is an optional extra item). Custom standing desks, some with treadmills, can cost considerably more.
If you don’t have room for a full desk and/or travel a lot, you’ll want to check out an upcoming Kickstarter project for the Ninja Standing Desk. It hangs from a door (with over-door hooks) or a wall (with drywall fasteners), and packs small enough to easily fit in a carry-on bag! Check out their video, and look for their Kickstarter launch on July 11th: [7/11/12 update: the Kickstarter is now live here]
