Chameleons Created by Chris Huntoon.
Chameleons move one square in any direction.
They may move a single step, or they may leap over a single Chameleon to capture it. A Chameleon that just captured may make another capturing move. Captures are compulsory. Any Chameleon that stays on a different color for more then one round will change itself to match that color. The central, spiral square is always considered to be the opposite color of the Chameleon that currently occupies it.
