Chime Viewer

Chime is a browser plug-in dedicated to molecular visualization. It is small, fast, and sophisticated. Chime has the flexibility to control and mix rendering styles down to the atom level (but needs a somewhat complex interface [using pop-up menus] to deliver that power). It supports several 3D chemistry formats natively, including (MDL) MOL and (Brookhaven) PDB files. Chime is available as a FREE download from MDL (see below).
