Yesterday it was cold enough on campus that we left Piper and Nika at home. They are both used to getting a walk around 10 AM, so I drove home, had lunch and let them out. When I got back to my office I remembered I'd left my laptop open (normally I put it to sleep when I'm at work or during the night). A quick Internet search and I found a command-line application that lets you take pictures using the camera that is built-in on new MacBook and MacBook Pro computers.
I used ssh to get to the laptop from work, downloaded the application, ran it, and then copied the image back using scp. I expected to either see nothing but the cushion of the couch, or maybe our cat Ivan sitting on the back of the couch watching birds.
Instead, it's Piper sleeping on the couch! She's not normally allowed up there, and whenever we've left her home, she's sleeping on her bed on the floor when we arrive. She's a sneaky one. A few minutes later I tried again, snapping the image of her actually standing on the couch looking out the window. When I got home later, I discovered we had a visit from some prosetylizing christians and that's why she was looking out there.
