I've uploaded the World's Worst Paint Program, as seen in my PDC talk, to IronPython's CodePlex site:

 http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=28125#DownloadId=93331

 This is built using Visual Studio 2010 Beta 2 and the IronPython CTP for that release - so you'll need to download both of those.  I've also included the Python and Ruby code that I used during the demonstration in a file called code.txt.  The paint program it's self is in the final form at the end of the demo.
