Those clever folk at Clancydocwra have come up with this marvellous new device for catching blind people and other social nuisances. The blind or visually impaired pedestrian is lured on to the white triangle. Next thing they are tangled in the trap and fall flat on their face in a heap of gravel! A simple, cost-effective device. Also rids pavements of people pushing double buggies and wheelchair users. (Exmouth Road E17)
