Exploring art is a great way to meet unexpected people out on the playa.Aly Weisman/Business InsiderAmong the 70,000 or so people who will make the trip to Black Rock City, Nevada, this weekend for the start of Burning Man will be some of the most influential people in Silicon Valley. 

Every year, some of tech's top execs join the annual festival, dressing in shiny costumes and exploring the art installations just like everyone else. 

The unwritten rules of the festival encourage anonymity and privacy. But the attendance of some of the CEOs and founders has been revealed by one of their enthusiastic peers on Medium. And many members of the tech elite have found their time on the playa — Burning Man speak for the dusty dry lake bed where the festival takes place — so life-changing that they couldn't help but speak about it publicly.

While nicknames and creative costumes often make it difficult to know if you've run into someone famous at the festival, a little knowledge can go a long way. These are the powerful techies known to hang out in Black Rock City.

Who knows? You might just run into one of them on one of the festival's famous art cars.Â
