A rather unusual exhibition of art can now be viewed in La Jolla at the Athenaeum Music & Arts Library. Yes, those shelves in the above photo are full of 3D printed “rocks!”
They’re actually a kind of lightweight plastic material, but they do resemble black volcanic rocks. Visitors to the Athenaeum’s Joseph Clayes III Gallery can watch a rock being printed and handle a specimen and consider the deeper meaning of Nolan Oswald Dennis: Demonstrations (i).
As the exhibition webpage explains, this collection of art, selected by The Athenaeum and INSITE from many entries, is informed by the study of geological and planetary systems—and situated within African and diasporic relations to the land, cosmos, and anti-colonial political structures.
A further description in the gallery includes: This artwork explores the political and spiritual history of the land in South Africa as a proxy for an after-history of the planet as a discontinuous but interrelated whole, imagining that we can use the digital shadow of a simulated rock (the thing without itself) to hold the immaterial social, spiritual and political relations which are also part of the geo-physics of the planet.
I’m afraid I’m not terribly sophisticated, so those explanations are a little beyond me. It struck me the exhibition is about something that is universal: the enormous complexity of essence and connection. That’s probably too simple.
Visit this very unique exhibition, turn over a simulated rock, and arrive at your own particular conclusion!
Nolan Oswald Dennis: Demonstrations (i) can be experienced through January 17, 2026.
