Ball & Stick for Mac

From Norbert Mueller:

Ball & Stick generates images and animations of three dimensional molecular models at atomic resolution from input files obtained from either structure libraries (e.g. protein data bank) or generated by experimental methods (e.g. X-ray crystallography, NMR,...) of by computatioanl chemistry (e.g. molecular mechanics, quantum-mechanics,...)

Who uses Ball & Stick?
People working in "molecular sciences" who want to publish graphical representations of molecular models (click for examples). What sets off B&S from other products in this area is the print quality achieved on moderately priced systems.
Technically this is due to the fact that we use a vector graphics concept up to the last step of rendering, which is done by the selected driver (display or printer).
