The Gagosian Gallery in Britannia St just off Grays Inn Road has an exhibition inspired by JG Ballard. It only runs until Thursday but is well worth a visit. You can see the pictures on their website here (not at all SFW). There's a Koons, a Lichtenstein, a Warhol and a Bacon. Jane & Louise Wilson's Proton Launchpad, a film of a disused Russian space launch area was particularly good.
