Recently I've gotten a lot of childlike joy out of writing simple programs to draw shapes (e.g. fractals), sending the output off to a fab shop, and getting laser-cut wood pieces of those shapes mailed back to me. There's something very, very pleasing about writing programs whose "output" is something you can hold tactile-ly in your hand. There's also something to learn in the process of optimizing a program for fabrication cost.
Project idea: Could you write a plugin or something that exports Snap! turtle paths to a laser-cuttable format (ideally SVG)? Or: has someone already(!) done this?
