If you use Darling models, there is no need for tape to fix the
peptide bond---the Darling models make quite good non-rotatable
peptide planes.  They are also excellent for showing hydrogen bonds.
What they are *not* good for is showing steric clashes, which I
believe was the original goal of the request for tools for teaching
about Ramachandran plots.

for specific instructional use of the Darling models for teaching
about protein backbones.
