["Gary McCallister" <mccallis@xxxx>]

I've written it down and will try to get over there. I will let you know in 
advance if I come that way.

We have sites in West and North Denver. The one I'd love to have you visit
is at 29th and Federal at Escuela Tlatelolco.

Cheers,

Chris

Where are you in Denver. I get over there occassionally. I know I will
bethere next spring for several days.

Gary,

Thanks for sharing. This sounds really cool. I'd love to see it run. I
had a chance to participate in Michael Tempel's workshop in Des Moines.
Grand Junction soon I hope! Do come visit our MicroWorlds based OpenWorld
Learning program in Denver if you have a chance.

Cheers,

Chris

My first project in Logo was to try and model a mosquitoes behavior
as it sought out a host for a blood meal. When I started I was really
trying to learn Logo and use mosquitoes (an organism I had been doing
reserach on for about 15 years) as a subject. Later I conceived of the
"Logo Life" project (as I now call it), which is a series of subprojects
exploring various biological phenomenon.
In the MosqHunt project I learned about such commands as "towards",
"touching", "colorunder", "random", etc. A small mosquito (visually a
tiny
black square moves at random. After each move it checks the distance from
another turtle (a tiny red square) that represents the host. If it is
closer, the mosquito continues to move at random. If it is further away
than previously, it moves at random "towards the host. There is also a
barrier that the mosquito cannot cross, but backs away from, then
continues
random movements. There is a counter that counts the mosquitoes moves
until
it find the host. When the mosquito is within 10 of the host the program
stops. The mosquito also draws a path with each move so you can visualize
the pathway. The host, mosquito and barrier can be moved to any position
on
the screen and the msoquito will still find the host within very few moves
(fewer than 50 almost always).
I would like to further refine the projects so that the host moves
also. I would also like to develop a similar project with StarLogo that
uses multiple hosts and mosquitoes, but that is another list server. :-)
I am sorry I cannot post this too the web. I am learning many
things
about Logo, but I still do not have a web page or know how to post a
project
that runs to the web. I could post the code if anyone was interested.
I have developed projects on such other topics as: turtles sensing the
environment, chaotic randomness and patterns that may arise, one turtle
chasing another turtle, recursion (many lower animals act recursively),
and
the growth of spirals as they are so prominent in biology.

Gary, could you tell us more about one or more of your "bioLOGOlogy"
projects
(or attach a project to share with us)? They sound fascinating.
