Back when I was handsome I used a webcam.  It was a long time ago but I 
remember one test was to do "cat /dev/video0"... or some other device 
(if dmesg and /var/log/messages don't say).  If you selected the correct 
device and had the permissions (you could try the command as a regular 
user or as root), that command would spew out (garbage) characters to 
the terminal while the cam was moving and seem to pause when the cam 
wasn't moving and pointed at nothing moving.  Ctrl-C or Ctrl-D gave the 
shell prompt back (as we'd expect).
