this program is an unique combination of two other programs - screensaver and desktop wallpaper generator. wallpaper generator creates custom desktop wallpapers for your pc every time when windows starts. real 3d models of biological molecules in random position are shown on wallpaper image. the screensaver shows the same 3d models of biological molecules in dynamics. your screen will look like screens of computers in science fiction films! for both programs you may choose any one from six total available molecule models and change axis of rotation. six molecules are available in the current version: four prototypes of dna (deoxyribonucleis acid - storage of genetics information) and two proteins - hemoglobine i monomeric (oxygen transport protein) and cytochrome c 550 (this protein has wide range of functions). in further versions we plan to add some new molecule models. note: only 2 models are available in unregistered version - dna in b-conformation and hemoglobine, other models available only in the registered version. models of protein molecules are represented only by the main polypepthide chain (-occn-); sidechains of aminoacid residues are not presented because they make the molecule look like a "heap of atoms". hydrogen atoms are not presented too due to their small size in comparision to other atoms.
