An exhibition of the work of Derek Jarman, including his famous film Blue, is taking place at the Serpentine Gallery. Blue was the last colour Jarman could could register before he lost his sight, and ultimately his life, to the disease. Much of the work addresses issues surrounding his sexuality and how he was impacted by AIDS. Curated by Isaac Julien, it runs until 13th April. And since the Serpentine is just up the road from Imperial you should have plenty of opportunity to visit before the show ends its run. You can find out more here.
