   Actually I always thought the jimp was jealous of those that provide
   content.   :-o

   How do lenses that concentrate light not violate the second law of
   thermodynamics? If you use a magnifying glass to burn ants, aren’t
   you making a point hotter than the ambient temperature without losing
   energy?
