The Alky Project is a set of DirectX 10 compatibility libraries, pioneered by Cody Brocious, a 19 year old software reverse-engineer from San Diego.
These libraries allow the use of DirectX 10 games on platforms other than Microsoft Vista, and increase hardware compatibility even on Vista, by compiling Geometry Shaders down to native machine code for execution where hardware isn't capable of running it. No longer will you have to upgrade your OS and video card(s) to play the latest games.
The current preview allows you to run a number of examples from the DirectX SDK on Windows XP. Future builds in the coming months will progress from demos to fully functional games.
