PyKinect (Yep, Python and Kinect, in Visual Studio yet!)

Credit for today's entry goes to Develop with Python in Visual Studio, connect with Kinect and Excel. I don't follow Python news much and so might have missing this if it wasn't for Dan's post.

Not only do does this highlight the latest version of the Python Tools for Visual Studio release, but shows off using Python to develop Kinect for Windows SDK games and applications. 

PyKinect – write Kinect games using Python!

We are very excited to announce PyKinect with PTVS [Python Tools for Visual Studio] 1.1. PyKinect enables writing awesome games and interfaces using Python:

Prerequisites:

• CPython 2.7
• PyGame (http://www.pygame.org/download.shtml)
• Kinect SDK (http://kinectforwindows.org/ 32-bit only!)
• Speech support (Kinect for Windows Runtime Language Pack, version 0.9)
• A kinect sensor (note you don’t need an Xbox 360 to use PyKinect)
• A kinect Power/USB Adaptor (eg: Sample from Amazon.com)

Installation:

Assuming you’ve already installed PTVS & a CPython interpreter, install PyGame, Kinect SDK and PyKinect (order doesn’t matter). To verify the installation, you can check: Tools/Python Tools/Samples/PyKinect -- you should be able use this to install PyKinect into a 32-bit Python distribution:
