The lego blocks were created from:
Buckytubes can be created via buckytube.py, which uses groups buckball1 and buckytube.
With an argument of 0, buckytube.py produces a buckyball. Arguments greater than 0 will add 30 atoms of tube section for each increment.
The crambin_diamond.pdb was created with the fillshape.py script, with 1crn.pdb (a protein named Crambin) as input. The result is a diamondoid molecule in roughly the same shape as Crambin.
The Kaehler brackets are created by scripts
which put together the kaehler_a_layer and (in the case of kaehlerb.py) kaehler_si_layer groups.
