I have been walking or standing for three days, and am working at TreeHugger founder Graham Hill's stand-up desk. True to his "less is more" aesthetic, Graham does not own a chair or stool, and my feet are killing me. Nonetheless, I have always wanted a standup desk, they are purported to be good for your back and for your productivity, and as an architect, that is how I used to draw.
Stilvoll of Germany makes one of the nicer ones I have seen, that has an unusual method of height adjustment, a pop-up sloping writing desk, pullouts and hidden trays, cable management and absolutely stunning workmanship. When my feet recover from this trip I want one. Video demo after the jump.
