Check out my first visual experiment with HaXe, an excellent new(ish) programming language that can compile to swf!
HaXe is awesome. It can compile to heaps of different targets (including flash obviously), and can be translated automatically to many programming languages, including PHP, ActionScript, C++, Neko, …
It brings a whole lot of awesome features to swf that aren’t even available yet in Actionscript 3, including inline functions, and direct virtual memory access (only currently available otherwise when using Alchemy).
Plus the syntax is very much like Actionscript 3, but more consistent. A+
Amazing.
