I once heard about some guy building a little enclosed area complete with toilet...you know, so he could stay inside World of Warcraft as long as possible. Thankfully this does not include a toilet. That would be too much.
Ergonomically speaking, I can imagine editing large batches of photos in a cushy setup like this. It reclines and everything. I couldn't help but imagine my Wacom tablet and a little RPG key set at my hands, racing through Lightroom for hours with zero pain.
