One cold winter in the 70s I was writing software for a payphone which had a 7 segment LCD. We were in Portakabins and turned the electric fan heaters off at night. Over the weekend the temperature inside dropped to -10 and the liquid in the LCD froze (it also turned my spider plant into something looking like my mother-in-law's completely overdone boiled cabbage). On Monday I arrived and turned the heating on; as the temperature rose the LCD slowly started to work again and the segments began to rotate, taking fully 30 minutes to go from one state to another.
