Andy,
Randall Beer did some great work on simulated cockroaches. Try the link
below to download a program based on his research. I don't think this is
the original program he developed, but it should be ideal for your purposes.
It runs in DOS I believe. Also, below is the information on his book.

Hope this helps.

| Howard, Since you are into mimicing the behaviour of an insect in some way, and I know that you are messing around with the Smalltalk Bot-Kit, you might like to consider the following for an idea. One of the interesting things about Bot-Kit is it (...) (26 years ago, 4-Dec-98, to lugnet.robotics)
