Need to investigate this further for my students—a language for writing LEGO-building algorithms, perhaps inspired by LOGO. There is a real need for more modern tiny languages (and One-Line Languages) that give children a taste of novel, playful creation. (Not the impractical abominations that code.org and such have given us.)

Seems like a dozen fascinating project could spring from this one. Are there similar projects that produce Paint 3D-style output?
