Mysterious Scavenger Hunt
Jejune Institute
Financial District

A mind-bending alternate reality is interwoven with the existing world. The Jejune Institute seeks to initiate the curious and usher them in with a series of Games of Nonchalance. Once one’s eyes are opened, there’s no pretending that one cannot see.

Pro Tip

First-time visitors should expect to spend a few hours learning the ropes. Bring two dollars and good walking shoes.

“Totally bizarre. Totally awesome. A San Francisco must do.” – Lauren F.

“Trust no one. It will change your life.” – Amanda C.


Spacing out on the commute home from work is a symptom of repetition burnout. Inject some intrigue back into the city and see everything in a whole new light. The Jejune Institute occupies office space at 580 California Street, but its mental space spreads to the edges of the known universe. This multilayered and intricately crafted participatory experience takes players all over San Francisco, responding to clues, text messages, events, and mysteries, all slowly revealed as the plot continues to thicken. Depending on your commitment, the fun can last from a few hours to a few years.
