Oh, you mean the ones that capture different aspects of human frustration? I saw some online, but I'm not sure what to make of them. These paintings seem to depict frustration in various contexts and forms. One that caught my eye featured a person at their desk, surrounded by work and deadlines. Their expression was priceless, a perfect representation of work-related frustration. I saw another one where an individual was stuck in traffic, visibly annoyed. The use of colors and the artist's technique really conveyed the feeling of road rage and frustration.
