I've been thinking about something like that for work. I spend all day sitting at a desk, usually doing computery things, and I don't think it's doing me any good. I always seem to have tight shoulders. I've considered getting a stool. I'm a tremendous fidget at the best of times - REALLY don't like sitting still - so maybe a balance ball would be a good idea. I'll go for Illicit Bacon. Seems appropriate.
