Nottingham had 'Light Night' – an evening of night entertainment and spectacle – for the fifth year. Although most shops close at their usual time, other venues open and have various events and light art. The trees near the Broadmarsh shopping centre were the first and last things I saw and showed that you don't have to be complicated to be effective.

After buying a ticket for a story in the 'lava lamp forest' at the Broadway Cinema, I had a wander around, including going inside the castle with its art gallery and museums for the first time (the usual entrance fee put me off).
