PDB 2HZV, E.R. Schreiter
This lovely crystal comprises a range of drawing styles — cartoons, molecular surface, spheres, and wireframe — and includes text.
PDB 1JX4, W. Yang
The polymerase enzyme is rendered as cartoon arrows with a molecular surface, so it's sharply distinguished from the wireframe DNA.
PDB 1MFR, E. Theil
The iron-sequestering ferritin protein, drawn as a smoothed spline backbone. This molecule is remarkable for its cubical symmetry.
PDB 1A0Z, A. Arnone
A historic and beautiful protein, hemoglobin is rendered here with ribbons for the peptide chains, wireframe for the four hemes, and a sphere accenting each iron atom.
PDB 1AU7, A. K. Aggarwal
This 19-base stretch of DNA is drawn as wireframe with dotted hydrogen bonds. A translucent molecular surface emphasizes the overall shape of the molecule, the major and minor grooves, without hiding the internal detail.

This very large structure shows the icosahedral structure of a virus capsid. In the 80mm cube there is just enough room to resolve the backbone fully.
