My Roomba is presently cleaning my bedroom and entertaining the cats
(who have figured out how to turn Roomba on)
I've read that Roomba is programmed with a dialect of LISP.
I've also read the Roomba technology is descended from the technology
used in bomb-disarming robots deployed in Iraq.
Going to be more of these devices I'm sure. And rebol *is* a
LISPish language, but much easier to use methinks.
