The LEGO system offers possibilities far beyond its core identity as a children’s toy.  In particular it allows for near-instantaneous experimentation with mechanisms, while at the same time allowing for sophisticated and beautiful constructions that demonstrate physical and mathematical principles.  I will demonstrate this by presenting some old and new inventions and discoveries (as well as a few mysteries) involving linkages, unusual gearing, mechanical computation, recursion and more.  I will also discuss practicalities of getting started with the medium as well as some of its limitations.
