For the assisted readymade Fourteen Slices of Time (2020) fourteen custom-printed postcards—souvenirs that trigger memories of Earth—are displayed on a simple stand that fits inside of an archetypal American mailbox. In postcard form, they become physicalized manifestations of strategic frames extracted from the video installation Timeslips. A streaming audio soundtrack can be listened to by viewers on their own mobile device while regarding the postcards, each of which has a phrase or sentence taken from the video’s voiceover on the reverse side. Taken in each other’s context, Timeslips and Fourteen Slices of Time act as triggers for considering the state of mind of an interplanetary agronomist—a lens for probing ethical entanglements that include altering the weather to protect vineyards, the Indian Removal Act of 1830, or planetary scale terraforming and biosphere transformation.
