Something else that TOTD saw in Cambridge last week was the Corpus Chronophage or Corpus Clock, an extraordinary sculptural timepiece outside Corpus Christi College.

An article on Wikipedia states that the gold plated face was created using the technique of explosive forming. The centre droplet, which you can see in the image gallery on the above site, is certainly remarkable.
