Opachess is a multiplayer (no AI) chess game implemented using the Opa Programming Language. This is my (Mads Hartmann Jensen) entry to the Opa Developer Competition.
NOTE: For some reason moving the chess pieces doesn't work in Firefox but it works in Safari/Chrome. My guess is that this is due to a bug in Opa.
I used Opa compiler (c) MLstate -- version S3.5 -- build 683 to build this. Simply 'cd' into the project root and run
make
make run

Once you've created your account you can see your profile at localhost:8080/user/{username}
