“Simulating Gestures,” a show in which Jessica Field questions the visibility of the artist’s hand in digital art, opens at Toronto’s Pari Nadimi Gallery. Field’s explorations of emergence are demonstrated here, by works including a simulation pitting artificial agents against one another (to make aesthetic decisions), and a recent drawing series where AI personas sketch “emotionally infused ideas to communicate” (image: Shame is only heavy when it hurts, 2021).
