This is an implemantation of a cool api for adding dynamic maps to web pages called OpenLayers.
The control in the upper left allows you to pan and zoom the map. Double clicking the map will center and zoom to the location where you clicked. You can also click and drag to pan.
The little plus sign control in the upper right expands when you click on it to reveal the available layers most of which are WMS layers.
I'll be adding functionality here when I have time.
