There are many pirate stories that have been told throughout history, my favorite one would be about Blackbeard the pirate. It is about what Blackbeard did to his crew when ever they made him angry. You see, Blackbeard had a tank that was filled with jellyfish, and whenever someone in his crew made him mad, he would simply throw that crew member into the tank and watch the agony that the jellyfish caused. The moral of this story is Jellyfish are calming. So a group of people created this Jellyfish lamp, it features three jellyfish that appear to swim around with a color changing background.
