Its the common tictactoe game, developed in java, with client/server configuration so it can be played over a network. It can be played in a 3x3 board or 4x4 board. There are more options but some of them are not implemented.
I'm only putting this here now (2012) but this was one of the projects for a University course in 2003, when I was still a student. I just thought I should put this some place safe, and so... here it is!
