Octopus in London

If you trip over a large, multicoloured Octopus in Thomas More Square, London, don't blame me. You have been warned. It's the work of Marialuisa Tadei, who is the best thing since sliced bread according to various art critics. Octopus has been installed by Land Securities, which owns the site, in partnership with Hay Hill Gallery of Cork Street. Metal thieves please note that its steel core is surrounded by concrete and hand-cut glass tiles.
