When the iPad was clamped to Kayla’s foraging board, she threatened with an open mouth and a series of outraged grunts. She reached out and touched the screen, painting her first stroke. Her indignation was soon replaced with intense focus, and she painted more and more, until the surface of the composition was covered with a network of strokes: short, staccato ticks; long, decisive swoops; parallel marks; many crossing at right angles. With the screen covered, she disengaged. When the iPad was removed, she attempted to wrestle it back into her possession.
