One evening, I stumbled upon a video of an elaborate cardboard LEGO minifig costume. As fantastic as it was, I recall thinking that “costume” was generous, as the person within couldn’t actually walk. I set out to design and build my own version, complete with fully-functioning legs. But I couldn’t make just *any* LEGO character… it was Halloween, after all. I decided to work in black (and sometimes, very dark gray). This is the story of the LEGO Batman of Boston.
