Bob 'Sick' Yudhita Agung, who calls himself 'Vincent van Bob', paints in the Primitive-Naive style with the graffiti of Jean-Michel Basquiat. He studied at the Indonesian Institute of Art in Yogyakarta where he received the Affandi Award in 1994. He was in the same batch as Ugo Untoro and S. Teddy D. His style is somewhat a bit like A.R. Penck, Eddie Hara and Malaysia's Chong Hip Seng. He showed with his former wife, Widi, at the Green Art Space in Yogyakarta in 2016. "I believe I can fly, with paint I believe can fly. Don't worry be happy," is his favourite refrain. He participated in the group show titled Life Records I, organised by Sin Sin Fine Art, Hong Kong in 2025.
