Although it may look like a salty version of the Iron Throne (and not by coincidence), this is actually a functional pipe organ made of cans of Pringles potato chips. Fall on Your Sword, an art collective in Brooklyn, made it for Gawker and Pringles.
It has 10 keys beneath spring-mounted cans. Pressing on each key plays a note. You can see it in action in this video:
A byproduct of this project was 6 bags of uneaten potato chips. Fall on Your Sword plans to soon reveal what it did with them. Since its members are artists, I'll guess that it's something more impressive than just eating them, which is what I would do.
