Cambridge and Oxford, again

Over the past 2 days we have gone to Cambridge and Oxford, staying with more family inbetween. At Cambridge we saw, among other things, an incredibly strange clock. It had something to do with Stephen Hawking (I can't remember, but it was on BBC News). The clock was a round wheel, with teeth around the edge. A pendulum swung which moved the teeth around. At the top was some kind of mechanical locust, which crawled along the rotating teeth as they moved. Check out the picture on Picasa Web Albums.

We also went to King's College Cambridge, but that was mostly ABC.
We stayed just out of Cambridge with more family. They had a cat called Bubbles who was very cute and cuddly, but she dribbled!
The next day we headed back into Oxford via a park-and-ride. I'm not sure whether this service is available in Australia, but the idea is that you drive there, park for free, and then catch into the town, easing road congestion due to bus lanes. At Oxford we went to go and see the Christ Church where the harry potter dining hall scenes were filmed. Also there was the main staircase leading to the hall, which appeared for the same purpose at the start of the first film.
Today we leave for London, which will be our last destination on our 'journey'. Not to say that it will be minor - we have lots of things to go and see.
