Rotationals is a book expressing the kinetic aspects of a windmill as it relates to printmaking and animation. During a residency in the Netherlands Klein was inspired by the many modern and antique windmills in the Dutch landscape. The industrious windmills with four blades were exquisitely engineered to pump excess groundwater and grind grain. These days many of the four-vane windmills are no longer functioning. The contemporary three-blade wind turbine dominates the landscape, gathering renewable energy from the wind.

In this book Klein abstracted the windmill vanes as a means to play with movement. Each page presents an image sequence of a windmill blade. The sequence can be animated through the mind’s eye or by using a GIF app on a smart device. —Sarah Klein
