Pushpin Mario is an amazing project which I just found out about (though it has been around since the end of 2008). This is the third revision of this project. From the first pin to the last took about two and a half semesters, though the final version was completed entirely within the first two months of Fall 2008. There are over 17,000 pins on the board, and the work was done entirely by students, mainly members of the CIS Student Association. The board is currently in the Student Computing Center at the University of the Fraser Valley.
