This program creates custom Desktop Wallpapers for your PC every time Windows starting. Real 3D models of biological molecules in random position are shown on wallpaper image. You may choose one molecule from six available rotation axis and image scale ratio. 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 available in unregistered version - DNA in B-conformation and Hemoglobine other models available only in registered version. Models of protein molecules are represented only by the main polypepthide chain (-OCCN-) none sidechains of aminoacid residues are presented because they make the molecule look like a heap of atoms. Also Hydrogen atoms are not presented because of their small size in comparision to other atoms.
