A while back, I had a chance to work on a project outside of regular work.  It started as a volunteer project to build a museum exhibit.  I met some talented people who were also committed to the project, and found some inspiration.  By the time the exhibit went live, I had relocated to a different part of the country.  A colleague who worked on the exhibit with told me sometime later that he was at the exhibit and it was crowded with a bunch of elementary school aged kids who were waiting in line to use the interactive joystick to move the exhibit around.  Success!
