PS2 Keyboard with Arduino

Hello I am working on a project and I need to count the keystrokes of a PS2 keyboard, I saw some article at sparkfun website and also a device built for that purpose but I need to do this with an Arduino Board as I am going to add some more stuff to respond those keystrokes.

Anyone have an tutorial / source that can share ? Or point me to a good place to start ?
Much appreciated.

Check the palyground:

There are 2 libraries that deal with PS2 keyboard / mice.

You could use the propelurino shield, it has a ps2 connector.
