I was just thinking about a friend of Mick's who is on his way back from Antarctica. While he's been over there (6 months or so) we have periodically looked at a web cam of the station where he was. We even got to see the ship that he was on come in when it arrived back in October - at the bottom of the page for each station is a time lapse of the preceding 24 hours. We knew the day the ship arrived because he emailed us as soon as he got there. It wasn't the best quality image but still.... amazing to see.

Now this got me thinking. Maybe there was a web cam of a canal or marina! I did some browsing and lo and behold, there's several of them. The quality varies considerably. The web cams at marinas seem to be the best quality images.
Here are some I've looked at to see the links are working and the picture is clear enough to see something.
Mercia Marina seems to be pretty clear : Click
Here is one at Aqueduct Marina : Click
