Glenn Horowitz Bookseller’s gallery Rare is currently showing the work of Sjoerd Hofstra with Karen O’hearn. On display are some of their artist’s books, featuring finely engineered kinetic elements. The subject matter of these books is directly mathematical. “A study in Averages” is a schematic treatise on the relationship between averages and society.

“Elements of Geometry by Euclid” includes pop-ups of the geometric solids. The mathematical texts have been blurred and instructional line drawings have been added.

“6 Empty Bookcases” is more architectural, but each of the bookcases presents interesting geometric 3 dimensional properties as it folds off the page.

What I find refreshing about Hofstra’s and O’hearn’s books is the clear unabashed connection to the mathematics. Whether addressing the societal implications of the use of averages, or creating their own interpretation on the historical Euclidean text, or using sophisticated calculations to build their geometric bookcases, the artists embrace mathematics.

I realize how difficult it is to see the true interactive nature of these books through my inadequate photos. The artists have provided a video link so you can see their work in action.
