Looks like a nice toy, but I could have told you that

...this would happen, because over time any particle of food would be left next to another one - there's nothing but the initial scatter that would leave it unheaped, so it will heap up.

Still just a nice toy - because no matter what you get, you always have this nagging doubt, "does it really do what nature does". I'd rather try a better rule - if you meet another gatherer, give him the food if his scent of home is stronger than mine. And anyone who receives food in this manner would turn 180 degrees and go in general direction of home(), drop it there and go out again. So these who happened to be at home() more recently are assumed to be closer to it. This would simulate a bucket brigade.
