I think that if you understand the idea of an agent variable, that
learning the concept of a patch variable is a freebie.

it also wouldn't have arisen if the documentation on patch vars had just
one more line in it stating exactly what Eric stated this morning. That
it's a variable for the 'patches' of ground. As soon as he set this
pointer, everything was clear.

Mountains and valleys are patches with a non-zero height and smoothly
joined to their neighbor patch.

everything IS just an agent, including YOU and THIS. The real question
is, what are we going to do about all the invisible people?! ;-)
