It hasn't gotten much use yet, but I've resurrected my old art project from a decade (!) or so ago--a simple trading box in the Fluxus
It's a tin box, 3 inches by 6, containing a variety of trinkets--a vial of glitter, and old wristwatch, a metal spinning top, and so on--and a ledger.
The trinkets are the kinds of things that acc**ulate in our purses and drawers, little items of arguable value that acc**ulate in the back corners of our lives.
Well, in the lives of those of us that live amongst mass manufactured flotsam and jetsam. I wonder, do people in more rural villages have similar collections of hand made items?
At any rate, the box is for trading--you pore through other people's items, find something you'd like, trade for something you have, and record the swap in the ledger. It acts minimally to keep some eclectic things out of the trash, and gives people a reason to reflect on the significance of what they're carrying... And for me, has reduced over time my tendency to waste money on acquiring more little trinkets. Not that I don't, but I do less of it.
Now I just need to encourage more of our guests to spend time with the box, and maybe find some places around town to plant new ones..?
