Hi savage.
No I haven't done something like this and I really don't intend to, since I'm not interested in all of them. I examine the managed examples for C# or VB.NET and I try to work them out in Delphi, for my own reasons (writting a game of course).

I hope that you will do it. (some of them are quite advanced)
It will be most helpfull for the Delphi community.
