Thanks to a commenter on my recent Lego Reuleaux triangles post for hipping me to the work of Lego builder Jeff Sanders, whose work with the unorthodox method of using rectangular Lego bricks to make complex curvilinear forms has reached levels of complexity and beauty far surpassing a few simple convex triangles. Wired’s GeekDad recently did a feature on Jeff, and Discovery News followed on with a story that emphasizes the “educational” angle.   [Thanks, Adam Brucker!]
