Well, if you find any. I believe Rhino when he says that people have tried and failed, although I'm more inclined to believe they gave up

As I said, you could do it yourself. There isn't source code for everything.

And BTW, VB can do pretty much as much as C++, but the more you get out of the VB "comfort zone" and into more advanced topics, the more roundabout and fiddly code you are gonna need.
