As Gioli enjoys saying, the cinema would never have been invented--indeed would not exist--with-out the sprocket hole, the perforation in the celluloid that allows the film strip to be pulled by mechanical claws through the camera's gate during exposure and, later, in the process of editing, contact printing, and projection.

Work-Order did add its own little touch to the revived logo by including 'Kodak' in bold, capital letters stacked vertically to the right of the 'K' to evoke the sprocket holes on the edges of film rolls.
It's quite an art to recreate the look of a Victorian or Edwardian photograph, and Paddywac, alias Marty Dowling, has done well, even if the sprocket holes are more appropriate to a 35mm frame from the early 1930s onward.

For the duration of the film, the central image is flanked by two rows of sprocket holes, which were created using a custom-built aperture gate that "worked as a sharp and precise mask." These sprocket holes figure forth the filmstrip itself not only as the material support for the image but also as the apparatus for its very projection.
The company also provides units for punching sprocket holes to the continuous stationery and label industries.
(Pieces from this exhibition will travel to the Venice Biennale this summer, where Mekas is representing Lithuania.) Printed from color slides, each of the "Frozen Film Frames" is an image of a strip of 16 mm film--usually three but occasionally two or four frames in length--typically including the row of sprocket holes on one side and the optical sound stripe on the other.
