Hi,
This could be very interesting for Squeak developing:

Description: ============ The Simple DirectMedia Layer library, or SDL for short, is one of the few freely available libraries available that is being used by commercial game development companies. It provides 2D framebuffer graphics and audio services in a cross-platform manner, supporting Linux, Win32, and BeOS. Other platforms, including Solaris, IRIX, FreeBSD, and MacOS also have varying degrees of support. SDL provides a simple API that allows you to get as close to the native hardware as possible, in addition to a large range of other services, including threads, endian independence macros, and CD audio. The advantages of using SDL are threefold: stability, simplicity, and flexibility.
