Finger Box or ?fingerbox? is a tactile art piece created by Ay-O in the 1960s. The boxes are small hollow cubes with a hole in the side. These boxes are filled with various objects, such as hair, cotton balls, nails. It is then on the art?s observer to put their fingers in the hole of the box. Online, people have used the box as a type of prank, where in which people ask about the box and others pretend to know what it is and to have owned one since childhood. When someone asks what the box is, others in the thread mock the person who asked.
