In this video, the birth announcement of the artist’s daughter is signaled with a vintage heliograph from 1943 (the year of the artist’s mother’s birth). The transmission reads, “Cicada Wen-Zhong Clark, Born January 21, 2015, 4:50 p.m., 7 lbs. 15 oz., 21” long. Mother and baby are well.” The video is shown as part of a triptych, along with the heliograph and a case of supplementary mirrors.
