Advance in snowflake growth simulation
Scientific American are reporting that “a team of mathematicians has for the first time succeeded in simulating a panoply of snowflake shapes using basic conservation laws, such as preserving the number of water molecules in the air”.
This explains that previous simulations often simulate the crystal surface using interlocking triangles, but that:
the triangles often deform and collapse in simulations, leading to singularities that bring the simulation to an abrupt halt… Garcke’s team got around this difficulty by devising a method to describe the curvature and other geometric information about the snowflake surface so that it could be appropriately encoded into a computer.

Perspectives of the regular solid
BibliOdyssey has posted some very old perspective drawings of polyhedra and other geometric shapes.
Geometric snow art
A man called Simon Beck has more than his fair share of free time and good ideas. He spends his days walking about in the snow at a French ski resort to create geometric patterns like the Sierpinski triangle, tilings of the plane and optical illusions. He posts photos of his works on his facebook page.
