An "art" exhibition called Psycho Buildings opens today at the Hayward Gallery in London. To mark its 40th anniversary the Hayward invited 10 wannabe architects from around the world to inflict "art" installations on the gallery. These include a boating pool, a transparent inflatable dome, a "disorientating passageway", a basement staircase created from a vibrant red semi-translucent fabric.... Need I go on? Clearly this piffle is designed to please mindless yuppies who know nothing about art and who crave fairground sensation, the same breed of twerps who injured themselves on Tate Modern's helter-skelter (CLICK). £10 for this tosh? You've got to be joking.
