Molekel is an open-source multi-platform molecular visualization program. 
Some of the features available in the new version are: 
Programmable shaders; standard shaders to enhance rendering quality, outline contours and perform sketch-like renderings are provided
Visualization of residues (ribbon or schematic)
Complete control over the generation of molecular surfaces (bounding box and resolution)
Visualization of the following surfaces:
    Orbitals
    Iso-surface from density matrix
    Iso-surface from Gaussian cube grid data
    SAS
    SES
    Van der Waals 
Animation of molecular surfaces
Animation of vibrational modes
Export high resolution images for 300+ DPI printing
Export to PostScript and PDF

Plane widget to visualize a scalar field: the plane can be freely moved in 3d space and the points on the plane surface will be colored according to the value of the scalar field: a cursor can be moved on the plane surface to show the exact value of the field at a specific point in space.
