QuteMol is described as 'open source (GPL), interactive, high quality molecular visualization system. QuteMol exploits the current GPU capabilites through OpenGL shaders to offers an array of innovative visual effects'. There are four alternatives to QuteMol for Linux, Mac, Windows, Wine and Android. The best alternative is Rasmol, which is both free and Open Source. Other great apps like QuteMol are pymol (Paid), Space Ball (Free Personal) and RasTop (Free, Open Source).
RasMol is a computer program written for molecular graphics visualization intended and used primarily for the depiction and exploration of biological macromolecule structures, such as those found in the Protein Data Bank.
Space Ball is brilliant, bright game that put you into the beautiful scenery of open space. Astounding 3 -d effects, many traps and obstacles will keep you busy for hours of playing. You want to know how to play?!
RasTop is a molecular visualization software adapted from the program RasMol, which was initially developed by Roger Sayle. RasTop is particularly adapted for educational purposes and for the rapid analysis of macromolecules at the bench.
