Dither is an algorithm that implements small random errors into the system (usually sound and image) in order to avoid the bigger unwanted errors. We forced this algorithm in order to (de)construct footages from old industrial landscapes of city Sisak lost in transition economy.





“...[O]ne of the earliest [applications] of dither came in World War II. Airplanebombers used mechanical computers to perform navigation and bombtrajectory calculations. Curiously, these computers (boxes filled withhundreds of gears and cogs) performed more accurately when flying onboard the aircraft, and less well on ground. Engineers realized that thevibration from the aircraft reduced the error from sticky moving parts. Insteadof moving in short jerks, they moved more continuously. Small vibratingmotors were built into the computers, and their vibration was called ditherfrom the Middle English verb "didderen," meaning "to tremble." Today, whenyou tap a mechanical meter to increase its accuracy, you are applying dither,and modern dictionaries define dither as a highly nervous, confused, oragitated state. In minute quantities, dither successfully makes a digitizationsystem a little more analog in the good sense of the word.”
