The program accesses your webcam every so often and grabs a shot of whatever is on the other end of the webcam. Then it emails you a report of where your laptop–or whatever electronic–is hanging out and the image.
Initially it freaked me out since this bright blue light pops up when the webcam is turned on; now I just ignore it.
Today Cara was sitting on my lap and I think the light caught her by surprise. What do you think?
