Bill Shaw creates and sells Lego Technic-compatible aluminum bricks.
It all started as a supplement to enhance Bill’s Mindstorms projects. All the elements are made to work with the original Lego Technic elements, but what makes them interesting is the fact of being made from high grade 6061 aluminum, instead of plastic. All the elements are designed in shapes not available through Lego, but that somehow may help you to solve some specific needs.
For instance, Shaw sells beams at nonstandard lengths and angled parts at different angles than Lego offers. [via technicbricks]
