There are scores of light trails in London, but few better — or cheaper, as this one is completely free — than the one at the Southbank Centre. Wise owls would combine it with the market nearby. Here on the Thames is a beautiful light trail to wander, with various artists using light and colour in playful ways. The exhibition features work by the likes of Samia Halaby, David Batchelor, Rafaël Rozendaal, France Lise McGurn, Jakob Kvist, and Nathaniel Rackowe.
