Anyone heard of or used this before?

The Cross-platform Toolkit

Haxe is an open source toolkit based on a modern, high level, strictly typed programming language, a cross-compiler, a complete cross-platform standard library and ways to access each platform’s native capabilities.

The Haxe programming language is a high level strictly typed programming language which is used by the Haxe compiler to produce cross-platform native code. The Haxe programming language is easy to learn if you are familiar already with either Java, C++, PHP, AS3 or similar object oriented languages. The Haxe programming language has been especially designed in order to adapt the various platforms native behaviors and allow efficient cross-platform development.

With Haxe, you can easily build cross-platform tools targeting all the mainstream platforms natively.

Haxe is like magic. Developers can publish native apps and games to every major platform without hassle.
