Actually, Forth was writen with just this kind of application in mind.

I had actually considered that but the way the machine works is almost exactly
like a turtle. It doesn't have direction but it moves freely in the X/Y
plane and has effectively penup and pendown so it looked like a perfect
match. SOmebody else has tried forth out on it already.

Speaking of logo sources, I've tried to get to anarres.cs.berkeley.edu
and my machine can't seem to find it. Anyone (Brian, maybe?) have the
Internet address?  Thanks a bunch.
