Dušan Kastelic was born in 1964 in Trbovlje. Very early on, he showed interest in drawing and storytelling. His first comics were published while he was in high school. By the time he studied at the Education Academy, he was already making a living with illustration. After finishing his studies, he started working as a teacher and then a few years as graphic designer. Since he got very interested in storytelling through images, he dedicated himself full-time to comics and illustration. In the following years, he published in all high-profile Slovenian magazines, mostly in Mladina, where they also published longer comics “Partizani” and “Afera JBTZ” that received a lot of attention.
Later, he developed an interest in new media and animated films, so he founded the BugBrain Institute for Animation, where he started making animated films and computer games with his collaborators. He is one of the pioneers of computer animation. His films, such as “The Box”, “Perk” and “Chicory 'n' Coffee” were screened at more than 300 international festivals and have received over 100 awards at home and abroad. In 2019, he received the Prešeren Fund Award. Currently, he is teaching computer animation at the School of Arts at the University of Nova Gorica.
