From today, if you happen to see a giant cardboard cut-out of a guitar, then you should know that it is your duty to interact with it. In a bid to liven up the streets of London, PSP presents CutOut and will deposit 500 1.75m-tall electric guitar silhouettes around town, designed by Peter Saville and complete with frets and dials. It is hoped that people will want to pick them up and play them, reinforcing PSP’s message of freedom and fun. ‘The guitar is the defining icon of electric pop culture,’ says Saville, who had an open brief as to what template he would design. ‘I wanted to design a super-sized cut-out for custom colouring and anarchic pantomime. I wanted to inspire people to feel like a child feeling grown-up.’ Fifty of the CutOuts will be signed by Peter Saville, but undoubtedly the real finds will be the 20 CutOuts that have been customised by 10 of the UK’s most hotly tipped newcomers from the fields of photography, art, graphic design, illustration, sculpture, textiles, product design, and silkscreen printing. An exhibition of the customised CutOuts will be staged at London’s Oki-Ni store from 21 July to 1 August. [Design4Design]
