Lightspark is a modern, free, open-source flash player implementation. Lightspark features:
* JIT compilation of Actionscript to native x86 bytecode using LLVM
* Hardware accelerated rendering using OpenGL Shaders (GLSL)
* Very good and robust support for current-generation Actionscript 3
* A new, clean, codebase exploiting multithreading and optimized for modern hardware. Designed from scratch after the official Flash documentation was released.
