To quote, roughly translated: Waninkoko has been working on developing PS3mlib, a high level library that provides application programming for PS3, including all types of basic features for video, audio, controls, camera, events, etc. This library will be released under GPL in a few days.
To demonstrate some of the functions supported by this library, he has created the application "TKC Demo 01", a technical demo for PS3 developed with the legal SDK "PSL1GHT."
This demo utilizes simple graphics drawing, playing sound files (using a SPU) and has support for the Playstation Eye (Eyetoy does not work yet.) You can interact with the application through the controller pad:
Up / Down: Increase / Decrease vertical speed TKC logo.
Left / Right: Increase / Decrease speed TKC horizontal logo.
START: Exit the application.
