The Star of David and stripes in this image are basically modified Sierpinski Triangles that have been duplicated "tiled" to create the design. Dedicated to Ze’ev.

Today’s Gratitude Item: ACD ChemSketch 11.0. Its a very nifty program that lets one create both 2D and 3D renders of organic molecules. Given that I’ll be teaching Organic Chem next semester, having this software is going to be extremely useful. Did I mention that the academic version is free? Life is good right now.
