programmatically take pictures?

[Steve Isaacson <steve isaacson gmail com>]

Is it possible to programmatically take pictures with Cheese? That is, 
without having a user Click a button.

I ask because I'm thinking about using it for security purposes. For 
example, to take a snapshot every five minutes.

If it's not currently possible, I'll download the source code and take a 
look.

Thanks
