Welcome to this page. We'd like to show off a mathematical model (the Rotor Router Model) using a java applet.
The model involves a bug (represented by an empty black and
while square) moving along a graph (represented by boxes
linked by arrows).
Each box on the graph contains a rotor that can be in different
states. These states are represented by colors and arrows.
When a bug visits a box, that box's state will change.
To get started, jump to the Applet and click the step button repeatedly and watch how the bug moves around the graph.
