While Tinei’s paintings are large-scale depictions of the fragilities of his models, the movie “Tmání” (Darkening), directed by Ondřej Moravec, designed by Bára Anna Stejskalová and produced by Hana Blaha Šilarová, uses virtual reality to show viewers what it’s like to live with depression. More importantly, the medium turns viewers into active participants, who can scream, shout, and whisper to interact with the surroundings.
