Back at the 1998 Lambeth Conference there was a webcam set up for spotting bishops set up at http://www.cs.ukc.ac.uk/events/lambeth98/ (unsurprisingly the link no longer works!).
I seem to have this one shot from that webcam:
I can't find an archive of other 1998 webcam shots - so far - anywhere on the web - though I think I did have a animated gif from it copied to a cd somewhere. I'll keep looking!
I can't find a webcam this time around, maybe they're keener on controlling the media - though the flickr photos are good!
