The video demonstrates the application on an EXO-PC tablet with the latest Windows 8 Consumer Preview and Visual Studio 2011 BETA. I started with a basic project that is provided with VS2011 and hacked it quite a bit. The result is very nice. Still bugs to work out but the speed is decent and it actually does work.
This app is not yet available to the public, but hopefully the Microsoft Store will open soon.
