Roller coaster

The engineers at our firm are designing the footings of this new roller coaster. (The ride itself is being designed in Germany.) I saved myself from drawing and redrawing hundreds of boxes by writing a Visual LISP program that reads the spreadsheets of design data, and then draws them for me. This is pretty "junior league" and is a simple program, but I have never worked with LISP before, so it was an exercise in "stare at it until it makes sense". Anyway, it feels good to circumvent a month of work.
