no its not.
I actually did something very similar to that for my first arduino project. (I take it its a webcam mounted on two servo motors.) ... Sadly that was before I started documenting my work or I would send you a link.
If I may suggest. You will learn a lot more, and spend less money if you use Processing & OpenCV or any of the Processing computer-vision libraries to implement this.
RoboRealm will also do the trick, in fact it will probably be easier, but you will only learn how to use a commercial software which (to my best knowledge) is not especially relevant in the bigger picture.

edit: in case you are not familiar with processing - www.processing.org (or something like that.)
