StarSqueak is built into Squeak images later than about Squeak 3.1. Just use

the "new morph..." menu, select "from alphabetical list" and select "StarSqueakAntColony".

It will take a few seconds before anything appears while the simulation is

initializing. Then a rectangular morph will appear. Use the red halo handle to

get a menu. In that menu, select "start" to start the simulation. I usually select

"keep this menu up" because it has several useful commands for running the

simulation.

You many want to use the "make parameter slider" to create a parameter slider

for "ant count". Note that with 50 ants, the ants tend to form trails to one or two

food sources at a time. With a much larger number, such as 300 ants, their are

enough ants to form stable trails to all four food sources at once.

P.S. The other StarSqueak simulations are also available in the "new morph..."

menu and can be run in the same way.
