The MoMA in Manhattan is presenting a retrospective of the Joan Jonas. Known for videos and installations that address political and environmental issues, Jonas incorporates blackboard drawings. Many of these white on black drawings incorporate mathematical images.

“Black Board Drawings III and IV” from 1971 features different vantage points of looking at a geometric shape, like an architectural diagram.

This drawing is part of an installation from 2002 titled “Lines in the Sand”. The step like pyramid form is related to both counting and geometry. Although these types of drawings were only a part of the total installation or video I feel it is important to point out the mathematical features of Jonas’ work.
