RE: [Swarm-Support] question about coloring of the background, and leaving paths

[Paul Box]

Another method used by one of my students here was to have each agent carry a 
list of the last five locations that it had inhabited.  Then, as the agent 
moved around, and as drawSelfOn was called by the agent (take a look at 
simpleOserverBug in the swarm tutorial), it drew itself on the raster, and 
then drew its last five locations in increasingly dimmer colors, giving the 
appearance of a trail fading into black.

demonstrate where he has been? I know I could do this by leaving an object and 
setting the color of that object appropriately, but that seem like a lot of 
work. I know also that in the termite program and a few others they appear to 
use another.
