Jonn Herschend has curated an exhibit called Sisyphus Office, which pairs Houston artists with office workers to "highlight art as an integral and necessary distraction in our day to day life".
I haven't seen the entire exhibit, but I really enjoyed David Fullarton's contributions. David created a series of small art pieces, made entirely out of office supplies, around the theme "What I do at work when I'm supposed to be working". Some of them are just too good, like the note to the financial department about microwaving halibut, or the apology note (shown above) explaining tardiness.
The exhibit is currently showing in Houston until July 27, 2009.
