Port Icons

[Argle2]

I was wondering if someone could anwser my question. I was looking at all the little port icons on the back of my case. I know that the trident like icon is for USB, the 3 connected computers icon is for networking, but I'm not sure what the icon of the baseball bat on the diamond is for. The port is bigger then a serial port I think. What is this port for? Thanks in advance for an help.

It is actually a picture of a joystick.

It is the integrated Midi/Gameport.
