Dear old MS LOGO
I genuinely did not expect an MS LOGO reference in Small Gods. Sir Terry’s got one for every season, as always.
Edit: MS LOGO is an implementation of the LOGO language. The entire language is a set of descriptions on how to move a turtle across the screen, i.e. controlling a turtle with electronic thinking.
There a bunch of very cool extensions to it, such as NetLOGO, and you can read more here.wiki
