Space Groups, Math and Chicks
got a chick from Moscow State University asking me about implementing Space group in Mathematica. Life's been worth living.

Anna, yes, you.
… haven't worked on this since 1998. I did 2D version. The 3D version would be much spectacular, especially with today's computing technologies (⁖ dynamic rotation in web browser). Also, going into higher dimension (⁖ 4th) would be a wonderful exercise in writing combinatorics programs or exploration into proof systems. Dimension 7 or higher hasn't been solved yet. Fame awaits!
