Pkviewer: 3-D Molecular Graphics Software

Pkviewer is a free, interactive molecular graphics viewer. The program was developed to visualize a sequence of 3-D snapshots of globular molecules that evolve in a constant volume system. It is appropriate for the observation of self-assembling systems, since it is able to distinguish particles that belong to an ordered environment.  While playing, the user can adjust the frame speed; change the view angle; move the point of interest and change the size of particles, among others.
