So i've been playing with GlovePIE and my old SIXAXIS for a while, pretty impressive stuff. Support for the DS3 hasn't been added yet, But the left rumble turns on if you do try to use it with GlovePIE.
If anyone has made any scripts paste them below. I'll start explaining some of the SIXAXIS functions as i figure them out.
