1+1=2 (2006)

Found machinery, calculator, paper.
(12 x 4 x 4 inches)

A motor is attached to a paper-fed calculator which prints on a single loop of paper. The motor drives gears which move an arm back and forth to repeatedly press the equals "=" button on the calculator. This action completes the equation "1 + 1" giving the next integer, which is simultaneously displayed on the calculator's screen and printed on the loop. One cycle takes about ten seconds. The calculator starts at one and counts upward by one, ad infinitum. Since the paper has been looped through the feed the calculator eventually prints over past computations, obscuring the printout. Only when the machine reaches a new decimal place (10's, 100's, 1000's, etc.) does the left-most digit again become readable for a brief period.
