Is there a way to turn off and On the isight camera or app to do it ?????

Hi

Does anyone know either of a Simple way to Turn off the isight camera on a Macbook pro (3.1 model with Snow leopard) or a simple program or Widget to do this ??

I have already Googled this but cannot find much - except disable certain files, or a Applescript by Techslaves.org called isight disabler , which seems great except I have to run applescript each time run this script, put in password, then select !
SO is there a Basic app or even a Way of making the isight disabler work like a simple app - or a way to do with Mac's settings ??

Any help is Appriciated
Thanks Mark
