David Chatting, December 2007

train_clock shows how the "shape" of the UK changes over the day with the coming and going of trains from Ipswich. Each of the "stars" is a different town, where its size reflects the population. As time passes towns move closer as a train is about to arrive and spring back when it leaves. The hands on the outer ring display the time. When shown the rings indicate distance in time, one ring per hour from Ipswich.

This uses real timetable data from one day in October 2007.

train_clock was built using the Processing language and an interactive version can be found at www.davidchatting.com/train_clock
