My previous standing desk was working just fine, it just wasn't in the kitchen. Kitchen gravity has been pulling me out of the spare bedroom/office and into the kitchen, where everyone else hangs out. Working on my laptop at the kitchen table was killing my wrists, so I mounted a proper setup to the wall. The LCD is held to the wall with an Ergotron Lx Wall Mount, and the Kensington 60044 Keyboard tray (also seen in my Ergonomic Workstation ), is mounted to a small shelf built from triangular brackets, 2x4's, and a plywood top surface.
It seems to be working pretty well, and the kitchen now appears to a have "helm."
I've got an Instructable in progress on the keyboard shown in the pictures, so look for that soon.
How to make a vertical, ergonomic tie-fighter keyboard is done!
