I arrived at the office this morning to find my co-worker eating cereal out of a paper bowl. Perhaps this is commonplace in other offices, but I've never seen anyone else do it here. I know what your next question is and no, he didn't use milk. That would just be a giant mess.
Anyhow, I thought it was a rather nifty office trick, so if you'd like to try it here's where Steve got his design.
