DreamChess features 3D OpenGL graphics and provides various chess board sets, 
ranging from classic wooden to flat.  A moderately strong chess engine is 
included: Dreamer.  However, should this engine be too weak for you, then 
you can use any other XBoard-compatible chess engine, including the popular 
Crafty and GNU Chess.  Other features include on-screen move lists using SAN 
notation, undo functionality, and savegames in PGN format.
