one simple cartoon design of a crowd

We want to have one cartoon design to display in case server is not available that has the same purpose as this for twitter: [login to view URL] We have the message "Too many users! Please be patient!" The ideas I have for this page are either a bus full of people and one person running behind it or a theater with crwod in front that can not enter. It needs to be obvious that the people are trying to get in but cannot. One peculiarity: We have site exclusively for intelligent people. Thus the people should at least to some extent people like Einstein and nerds. Also this might be reflected in what is written on the bus or on the theater hall, if you use our ideas. The best way for us to evaluate you is for you to give us a look on your portfolio. We would expect this to be a one day job maximum.
