This ceramic rug by Claudia & Julia Müller transforms a school hall through material deception. At first glance, it appears to be a soft, woven carpet with long fringes, but it is actually a permanent installation of glazed ceramic tiles set into the concrete floor. The work cleverly plays with domestic comfort and institutional space, using the familiar object of a rug to alter the perception of a vast, functional hallway. Its title, a direct quote from the film The Big Lebowski, injects a layer of pop culture wit, suggesting how an ordinary item can unexpectedly define an environment. By being laid slightly off-axis, the rug creates a subtle tension and reorients the flow of the space without obstructing it. The handmade quality of the tiles, in ten different colors, adds a tactile, artisanal warmth to the hard architectural setting, making the school's common area feel both anchored and strangely inviting.
