Born in 1974 in Frankfurt, Stefanie Herr initially worked as an architect and architectural model maker. But since 2007 she’s been experimenting with photographic relief sculptures to make a point about economic and environmental sustainability.

Currently living in Barcelona, the visual artist’s latest project explores the spatial dimension of stock charts by translating their peaks and valleys into physical coordinates. Completely hand-crafted out of cardboard, aluminium and paper, each piece of the series took about two months to complete.

The piece is intended as a statement about the idea of infinite economic growth on a finite planet. To create it, she mapped the performance of the S&P 500 Pure Growth Index over a six-year period between 2009 and 2015 and transposed it into six sculptural objects covered with photographs of forests.

“The forest is the place where growth is inevitable and vegetation luxuriates,” says Herr. “It is a multidimensional space that expands both horizontally and vertically and devours everything within its boundaries.”
