I just finished my presentation at Flashforward2007 Boston and absolutely loved it! My session covered the basics of object-oriented programming with ActionScript 3.0 and a little introduction to Design Patterns (Observer, Singleton, MVC). Managed to get a full room with Aral Balkan presenting next door so am pretty impressed about the turnout. Great audience response and questions afterwards so, thank you Boston!
As promised here are my session notes for download, I'll be posting a more in depth example of MVC with AS3.0 in a couple of days. Enjoy!
