E-Chick - Wow! When I saw the gif I remembered "borowing" one exactly like this for a college project I recently completed.
For the past two days I have been searching frantically for the source. Finally found the website to the gif: http://www.geocities.com/SiliconValley/Network/2260/Gifs.html
Slim - go easy on me...I hope this helps.
Regards,
