Years ago, I saw a news clip featuring Salvador Dali

The flamboyant surrealist artist, with his trademark handlebar mustache,
- he was famous for his painted landscapes with melting watches
• he had alerted the press that he was working on another masterpiece
◦ and he was going to complete it in front of a live audience
• the day came, and a crowd gathered and the cameras were rolling
- Dali arrived with his usual air of self-importance
• he dabbed his brush in a smudge of white paint,
◦ climbed a step-ladder, and with theatrical flourish,
◦ added to the portrait of a woman, a dot on the pupil of eye
• that was it – the painting was finished
