This is my first try at collaborating with you.

The tile board to the left is persistent: Any changes you make to it will remain for anybody else who comes to this page.

As different people play, interesting patterns might emerge.

Of course eventually there will be cool things like critters moving along the lines, but we're going to build up to that. :-)

Instructions:

• Click on a tile to rotate it.

• Drag between two tiles to swap their places.
