The Seeing Machine

We are at war with the insidious seeing machine. We seek ways to blind it.  We try and we fail.  Billy convinced us to keep trying.  But applications of radioactive ink have led to mixed results. Brian became invisible, experienced no ill side effects, but was only invisible for 12 hours.  Bill applied radioactive ink to his hands, became ill.  The cost of his sickness exceeded the benefit of his invisible hands.
