Logo is a very simple programming language, devised by SeymourPapert as a teaching tool for young children. Logo is most familiar as the language used to control a turtle trundling round a classroom floor, but it is in fact a fully general-purpose language, with variables and subroutines. EricRaymond refers to LoGo as "stealth LISP". See: - http://el.www.media.mit.edu/groups/logo-foundation/ The Logo Foundation - http://www.yukoncollege.yk.ca/~srudge/comp052/grcom.html a command summary LoGo might be the language with which to create WikiDiagrams; it's simple to use, powerful enough for the jobs we want done, would be easy(ish) to write an interpreter for, and has _hardcore_ old-school associations. _Indeedy. How many people here actually had a go with those *really* cute green plastic turtle-shaped robots which could be used to draw Logo designs on huge pieces of paper? --TL_ Oh yes... we had one permanently set out on a huge table. It probably taught more than half of us how to use a computer. I'd vote for it! _(As a Wiki tool, obviously... although it might make a decent MP as well.)_ -- WJR I've seen those sort of dodecahedral transparent green plastic ones. They're pretty cool. My school only had the one that looked like an upturned salad bowl, though. -- TA CategoryGeekery
