The exhibition "Kastanis and the Universe" features a conceptually spiraled arrangement of Robert Rūrāns' works, with early pieces displayed at the periphery reflecting on social and political themes published in both local and international media. This display gradually leads to the exhibition's center, which reveals a new vision of the artist inspired by medieval traditions, as well as the specific portrayals and symbolism of Orthodox iconography.

Both the exhibition's poster and title illustrate the artist's shift in focus—from a sharp observer of social-political life to an inward-looking believer who aims to perceive the deeper purpose and place of even the simplest things within a larger narrative of existence. This transformation highlights Rūrāns' evolution and the broader implications of his artistic journey.

Robert Rūrāns, a Latvian illustrator and artist born in 1990, initially found his passion in street art, particularly graffiti. His artistic education at Janis Rozentāls Art High School led him to develop a keen interest in graphic arts, which further evolved into his study of illustration in Creative Art. This exhibition showcases not only his artistic development but also signals significant thematic changes in his work, encouraging viewers to reconsider the intersecting layers of life and art.
