Mitch writes in about Greg Blonder, who made this prototype slide rule clock with LEGO Mindstorms. The positioning of the two rules makes up the hours and minutes. I like the idea of sketching in a platform like Mindstorms; it sure beats building an entire custom circuit just for a proof-of-concept prototype.
