How to place code snippets within Visual Studio 2010 Toolbox window?

I've really enjoyed Anders Hejlsberg presentation at BUILD 2011 and it's not the first time that I notice someone having a collection of code snippets available within Visual Studio's Toolbox window, so given that all the searches I've performed so far pointed me to how to deal with IntelliSense snippets, I was wondering if anyone knows how to achieve this?
