If you're into spots (sorry, "pixellated mosaic tiles"), then a Frenchman who punningly calls himself Space Invader is the artist for you. His first UK solo exhibition opens at London's Lazarides Gallery - run by Banksy's agent Steve Lazarides - on 5 October. The gallery is more interesting than its art. A former Soho sadomasochists' boutique, it retains its dark red walls and a sign that points to the Dungeon. Maybe that's where they whip you into signing your cheque. "Stop! I'll buy it!" Crack! "Mercy! Two!" Crack!
