Water on Glass

Today has been cold. The thick frost this morning is still present this afternoon on parts of the garden where there has been no sun. It's probably not unusual in many parts of the country but is less common in the far south-west of England. 
Today's blip shows condensation on glass. The outside reflections in the water droplets came as a bit of a surprise! In some ways they seemed to take on the appearance of the flints found in areas of chalk bedrock.
