B-Squares: Lego for electronics

B-Squares: Lego for electronics: "Connecting blocks are one of the all-time greatest types of toys. Unfortunately, when we grow up, many of us seem to think that it's silly to make stuff just for the sake of making it – we still enjoy putting things together, but they have to be functional. That's where B-Squares come in. The flat electronic modules serve a variety of functions, and can form a variety of devices when connected in different combinations."
