Is there anything that could make my playstation controller a mouse?

[recondite7]

I have no idea if this is possible but I really want to get a new mouse setup for long sessions of poker. I think my playstation dual shock controller would be perfect but I had no idea if there is something that convert it to usb for use on a computer and if it would function as a mouse.

Any help would be appreciated and any other solutions welcome as well.
