"Untitled 5" was hand drawn using Adobe Photoshop by my former graduate student Katherine Jones-Smith to investigate this very question.

That claim unravelled when "Untitled 5" was found to be an authentic Pollock according to the fractal criteria. As a result "Untitled 5" has appeared in a publication in 'Nature,' in newspapers around the world and in a textbook on Chaos theory (but not yet in an art gallery). Meanwhile the answer to the question posed above: not yet. Show less
