There's a cool python library for machine embroidery called inkstitch, but I love the idea of using a gameboy..

It seems like there could be some interesting ways to teach programming using machine embroidery. So, eg, kids program a pattern, and then get to stitch it onto a hat. Feels like an area with a big pay off right away, but also incredible depth (eg turning an image into a stitched pattern).
