I had a coffee mug that has a chalkboard coating and a piece of chalk. Everyone knew my current mood by the smiley, neutral, or frowny face depicted. Only once did I have a post-nuclear face, and that was when someone in the office introduced a virus through an infected e-mail he was specifically warned not to open until we got the anti-virus updated. Irretrievably lost several hours worth of work that day. Twitbrain is no longer with that company.
