UPDATE: OpenNI has a new site so a lot of the links (and some instruction on how to obtain things) have changed.
Mac OS X
Uses Kinect to control which beat is playing in a looping sample. A sample is chopped up into eighth note slices (or any increment) and arranged like a clock face around you. The currently playing slice is controlled by your left hand's position in space. This allows you to remix a loop by waving your hand around. The red dot indicates your hand's position, the green bar indicates the currently playing slice, and the blue bar moves at the tempo of the song to serve as a guide.
Ryan Challinor wrote an incredibly useful tool for speeding up the set up process involved with using your Kinect sensor with Apple's free visual programming tool Quartz Composer.
Mac OS X, Windows
Our dev bundle installs the latest versions of OpenNI, a general-purpose framework for obtaining data from 3D sensors, NITE, a skeleton-tracking and gesture-recognition library, and the SensorKinect driver for interfacing with the Microsoft Kinect. It then configures them all to play nicely with each other, no command-line wizardry required!
Synapse is an app for Mac and Windows that allows you to easily use your Kinect to control Ableton Live, Quartz Composer, Max/MSP/Jitter, and any other application that can receive OSC events. It sends joint positions and hit events via OSC, and also sends the depth image into Quartz Composer.
This package is truly a life saver. A quick and convenient way to download all the dependencies required to properly compile and build libfreenect on your Windows machine.
Includes OpenNI, NITE and PrimeSense Sensor Module. 32 and 64 bit versions
This handy little package will allow you to easily install the OpenNI and drivers and Brekel Motion Capture software in one clean, easy swoop. I've also included the Motion Builder plugin and the stand alone version of Brekel Kinect.
UPDATE: Forget about all that, the ZigFu package installer is flawless and by far the easiest way to get your Kinect working with your computer and it takes all of two minutes.
