If you follow this blog, you know how much I love marbles. I was staying up for Microsoft's It's Time To Share event and I thought I'll write up a C# version of Colliding Marbles. It's a pretty straight forward port from the native version, the only major difference being in the drawing primitives. Video follows. The solution was created using Visual Studio 2008 and the source code is shared below.
