triskelion: Celtic symbol The triskele, otherwise known as the triskelion, is a three-pronged spiral, and is often used as a basis for more complex spirals. Some suggest ancient Celtic triskeles represented the Triple Goddess of the three ages of womanhood. It later came to represent the Holy Trinity in Christianity - God the Father, Son and Holy Spirit. Whatever its� meaning, it is interesting that the motif is based around The Number 3 - regarded as a highly sacred number in many ancient cultures, not least The Druids. www.irishastrology.com/skyship

Self-assembly of three-legged patchy particles into polyhedral cages The self-assembly of rigid three-legged building blocks into polyhedral cages is investigated by patchy particle simulations. A four-site anisotropic interaction potential is introduced to make pairs of overlapping legs bind in an anti-parallel fashion, thereby forming the edges of a polyhedron of pentagons and hexagons. A torsional potential, reflecting an asymmetry or polarity in the legs' binding potential, proves crucial for the successful formation of closed fullerene-like cages. Self-assembly proceeds by a nucleation-and-growth mechanism, with a high success rate of cage closure. The size distribution of the self-assembled buckyballs is largely determined by the pucker angle of the particle. Nature explores a similar building block, the clathrin triskelion, to regulate vesicle formation at the cell membrane during endocytosis. iopscience.iop.org/0953-8984/22/10/104103skyship

Sky,
I think I have photos of the inside part shown at 1:28 - I called them a "steering wheel"... I'll post them soon.
