Creating searchlight effect


Richard Woodard

What I would like to do is to create a spot light that simply sweeps back and forth from left to right, and slightly up and down in an oval like pattern - like a search light, complete with that cone of light (I am sure it has a technical name, I just don't know it.) Think of the Bat Signal from Batman.. just with movement to it. Links to any tutorials on the matter, or any sort of suggestion would be appreciated. Thanks.
