auditorium, to let us know what was going on in other corners of the
company.  I remember one talk was illustrated by two 4x8 sheets of plywood
painted white and displaying all the different connectors used on our
products.  The presenter did give a talk, but he really didn't need to
say anything.  The message was clearly, "Before you release yet another
connector part number, look at what we already have."
