Distance field based decal rendering
Rim van Wersch shares an XNA Framework implementation of the Valve paper Improved Alpha-Tested Magnification for Vector Textures and Special Effects, presenting “[a] simple and efficient method […] which allows improved rendering of glyphs composed of curved and linear elements.

Geodesic Grid
Brian “JeBuS” I-Don’t-Know-His-Last-NameSchaeflein published a multi part article about Geodesic Truncated Icosahedron (part 2 is here, part 3 is pending) in C# and the XNA Framework. Geodisc Truncated Icosahedrons are “a shape made of hexagons and pentagons” that “has as many faces as needed to make it as spherical as needed, like a Geodesic Dome”.
Head over and grok the code for fun and profit.
Also note his disclaimer in the first post:
I don’t claim that my way of programming is the best way. As far as design patterns and whatnot go, my way works for me, and the code gets the job done. If anyone can offer a more “elegant” approach to anything I’m doing, I’m all ears.
