But as Lewis Biggs, one of the festival's curators, told the BBC, it's still pretty hard luck. "There are 30 gold bars buried there, along with a lot of washers, so if you bring your metal detector you will find a lot of washers before you find any gold... We will never know if the gold has been found or not".
Well, gold bars actually look a lot different from steel washers. But OK.
The bars are also scattered over a wide area on the bay, while the troublesome tide only lets diggers search at low tide after 4pm, with an hour before closing.
If you fancy your hand at striking gold, Sailstorfer's installation is up through Nov. 2.
