Artist and designer Es Devlin’s PoemPortraits is a social sculpture that brings together art, design, poetry and machine learning; it has been created in collaboration with Google Arts and Culture and Ross Goodwin. Each visitor is invited to donate a single word to the piece. This word is instantly incorporated into a two-line poem generated by an algorithm trained on 20 million words of poetry. This poem will form the photographic flash that illuminates each unique PoemPortrait.The work is cumulative; each poem will also include a word donated by another visitor. At the end of the exhibition, a collective PoemPortrait will be generated from everyone’s contributions: a trace of this transient social sculpture.The Barbican
