A missing message from rogue mathematician Alan Turing surfaces as part of the celebrations for his 100th birthday. In code, it provides the key to a century old puzzle that, if solved, will bestow academic immortality...and crash the world into chaos.

This commission brings together two artworks made almost 100 years apart. Both works were produced for the same room in Tate Britain. One is a mural, painted directly on to the walls of the gallery in the 1920s. The other a film installation, commissioned in response to the mural. Together these artworks invite questions about how we engage with artworks from the past.
