Artist Scott Jarvie doesn’t believe home goods need to be warm and inviting to earn a spot in the house. That’s certainly the case with his mind-bending void rug: When viewed from a certain perspective, the interior design piece inspires feelings of dread rather than comfort.

According to designboom, Jarvie achieved the rug’s bottomless black hole illusion using clever, two-dimensional design elements. To people standing directly over it, the item resembles a shaded crescent moon cupping a flat black circle. But adjust your position, and the simple rug morphs into a stomach-turning void in the middle of your living room floor.

If the circular rug isn’t trippy enough, Jarvie also made a rectangular runner that can turn an entire hallway into an empty pit. Neither rug is something you’d want to forget you own on a midnight trip to the bathroom.

Jarvie’s art isn’t limited to floor rugs that trick the eye. The Scotland-based artist’s creative furniture and home decor includes laundry balls, a cling wrap dispenser, and a chair made from 10,000 plastic drinking straws.
