These stalactites aren't natural formations eerily hanging from the ceiling of a cave, but free-standing futuristic structures from the Upright Series of New York-based Pink Inc. This fabric series includes such innovative shapes as Delta Ray, Asterisk and Future Tunnel. Made of spandex, they are lightweight and easy to store. You also can have your logo printed on them.
