What's the deal with the table?

A few weeks ago I posted a picture of a table in my office and left you wondering what it was... Please see below for a current picture of my table.  You will notice student names written on it.  As I get to know students through visits to my office, announcements, etc. I am asking them to sign my table.  I hope that it will be filled with names of Barrows students by the end of the year!
