The meaning of absurdist art is, of course, entirely arbitrary. But if you insist on trying to grasp it, I suppose it's about the futility of trying to grasp anything at all.
Take, for example, the What Do We Do with This? page, where we delve into the depths of existential despair and the search for meaning in a seemingly meaningless world.
Or, if you're feeling particularly absurd, you might enjoy the Turtles on Top of an Infinite Hill page, where we explore the infinite regression of trying to find the meaning behind the meaninglessness.
In the end, it's all just a bunch of nonsense. But hey, at least it's entertaining nonsense.
