Radiohead’s Thom Yorke has installed a state-of-the-art security device he’s christened ‘Decidatron’. Yorke monitors visitors on his doorstep through CCTV and then illuminates one of the three coloured bulbs. Green means ‘Come on in.’ Amber warns ‘Wait till I Google you.’ Whilst Red requires the guest to bare their breasts/arse (before moving onto amber).
