Federico Diaz "Geometric Death Frequency-141" at Mass Moca
from article, "robots, machines made to produce a sculpture without any human hands."

Roxy Pain's , Paint Dipper and Scumack are the same thing.

Does Diaz's differ in the technical differences of how its made - where does the diff./similarities lie? At first, with the numerous black balls and the static motion of the piece - i got a feeling of darkness. The title attributed to that too...

Roxy Paine (wikipedia):

In his body of work, Roxy Paine mirrors natural processes, drawing increasingly on the tension between organic and man-made environments, between the human desire for order and nature's drive to reproduce. His highly detailed simulations of natural phenomena include an ambitious series of hand-wrought stainless steel trees, vitrines of mushroom and plant life in various states of decay and several large-scale machines designed to replicate creative processes. Collectively, his works demonstrate the human attempt to impose order on natural forces, depicting the struggle between the natural and the artificial, the rational and the instinctual.

..."book made into a film"
In the case of Geometric Death Frequency-141, the "book" is a digital photograph of the museum's clocktower entry courtyard as taken by the artist, which the artist then transforms into pure data, and modulates using analytical and fluid dynamic modeling techniques, finally rendering the data stream into a three-dimensional sculpture using state-of-the-art computer-aided manufacturing methodologies. The new work thus combines elements of photographic manipulation, data analysis, and computer programming, utilizing new techniques to produce a sculpture completely untouched by human hands.

That the sculptures were made without human hands is not what Diaz seems interested in after all.
His is more of a remaking of an object that exists into another object/image.
