Or, well, I should say, she's participating in one.
Next Saturday, the 26th, and it's a fundraiser for a good cause - to help one of her friends raise the money for his documentary, and also to help do some sort of 'day-camp type thingie.' The important thing here is that she is selling off most of the artworks from her gorgeous installation piece What Happens. This is one of my favorite installations that involves postcards, found artifacts, and a scientific frame of mind.
Here's her original post. It's in Los Feliz, which is central to the whole world, so you have no excuse for missing it.
