This is so simple, yet so genius. Perfect user experience design.

The urinals in the toilets on the Schiphol Airport in Amsterdam, has what looks like a small fly inside of them. When you look closer however, it’s actually the outline of a fly, etched into the porcelain itself. The staff at the airport did research afterwards found that urinals with the fake flies reduced spillage by 80%! When a man sees a fly, he automatically aims at it. Genius.
