Daniel Libeskind delivered the annual Lubetkin lecture last week to a packed house and tumultuous applause in Kensington Town Hall. Questions from the floor, however, failed to match the high standards set the maestro. First up was a query about how he felt about Frank Gehry being featured on The Simpsons while he hadn't. Libeskind reckoned that Gehry was a more suitable shape and looked better in yellow. But any relief that one of the next questions was posed by an elderly gent was shortlived – it took the form of an enquiry into orgiastic architecture and masturbation.
