Added a cron script to rename the webcam output:

streamer -o cam.jpeg 2> /dev/null

streamer -o cam.jpeg 2> /dev/nulmv cam.jpeg cam_date +%y%m%d_%H%M.jpg

This gives the files a name like cam_070118_1035.jpg. I took a series of these, combined, them, and got a cool time lapse movie of the sun going up and then down again, from the viewpoint of my basement. Well, not an exciting subject, but a cool beginning.
