Update 02 02 2009
Much optimized code, up to 5 times faster.
Adjust "-width" or "-heigth" in command line or in startup script to gain more speed.
Works properly if workbench depth is set to 16bit.
The SDL Sand game (The Falling SDL-Sand Game) is a C++ implementation of the original 'World of
Sand' (and later 'Hell of Sand') game implemented in JAVA. SDL Sand uses the SDL (Simple DirectMedia
Library - http://www.libsdl.org/) library for screen output. Therefore the implementation can
possibly run on every platform supported by SDL.
The aim is to create a faster implementation of the game and possibly extend its features.
