I finally got around to hacking a Gesture Cam onto a Rift (big thanks to Herbst for the plugins!), so I could use my hands in VR land:

It does a pretty decent job of tracking hands and fingers, except the DS325 field of view is somewhat less than presented by the Rift, and in order for the PCSDK to initially recognize your hands you have to bring them up in front of the camera. But it is cool having your hands in VR!

I could even touch my fingertips together:

Pretty simple to do really, but I can post the patches if anyone’s interested. And it gets really fun when you use a Primesense/Kinect for head tracking and can walk around and touch virtual things…
