Hi, all. I'm new to the list but intrigued by the discussions. The
particular bit preceding caught my eye, and caused me to wonder whether
anyone had attempted a macro-level analog -- what comes to mind would be
assemblers/disassemblers for lego structures.
Has anyone ever tried to build a machine which could take a lego object,
and build a copy? Or duplicate an object in any similarly constrained
