First attempt
growing unlayered-graphene in digito
Growth began with randomly-oriented pentagonal
seeds. How big is the black cube? Is the carbon-carbon
bond length correct? The atoms outside the
cube are "overflow". What's the density of atoms in the
cube, and how does it compare to that of graphite?
