What fun you can have by pointing a camera at a monitor displaying the video feed from that camera.
Enjoy.
You can do this with VNC if you’re not lucky enough to have dual monitors. Beware though, you can lock up your system if you use VNC. So save stuff first. 
Very nice. And strange. And creepy.
/vimeo ftw/
What was that … Vimeo? I wonder who told me to use that?
I love doing the thing with VNC. It’s the ultimate boredom buster!
Vimeo looks interesting. It’s good that someone’s managed to find a niche alongside YouTube.
