The amazing ice graffiti found after a freezing cold night

Jack Frost has a decidedly mischievous streak in his character, it seems.For when Robert Baker went outside on Wednesday morning, he found his car had been sprayed with dramatic ice graffiti.Frost had tagged the windscreen and roof with the characteristic fronds and swirls of fern frost, which forms during the coldest nights.
'I couldn't believe what I saw,' said Mr Baker, 76, who had intended to defrost his wife's Rover 45, in Folkestone, Kent. 'I called to my wife Julie to have a look.'The pattern was one bit of graffiti he didn't mind seeing. 'Usually I would have defrosted the vehicle fairly quickly but the ice formations were stunning,' he said.'They didn't last long - they were gone as soon as the sun came out.'
It appears the ice artists were out in force.In Oxfordshire, Stuart Dent found similar patterns on his Jaguar.Car windows and paintwork are good heat conductors and water droplets often form in very cold weather.Tiny imperfections such as scratches and dust influence their arrangement, so when they freeze, they form beautiful patterns.
