Here is the new attraction of Cambridge, a mechanical clock encrusted in the walls of the Corpus Christi College. This clock was unveiled by Professor Stephen Hawking in September.
It's next to Kings College to King's Prarade, then it was already all the time now tourists flock can practically across the street so there are people who take pictures! For now I have not understood how bed earlier, I think there is a small blue light that ride on each circle of small strokes .... one for the seconds, one for minutes and one hour. We see better at night. If you want more information read the article in the Guardian here.
