Harvard University lecturer Matthew Kaliner creates otherworldly beach sculptures that are unlike any other sandcastles we’ve seen. Rather than stacking up architectural structures or realistic figures, the artist designs surreal, curving compositions of sand that are suspended in midair. “I am motivated entirely by the sheer joy of playing on the beach, and making something out of what I can find that day,” Kaliner told The Atlantic. The sculptor is particularly drawn to building pieces that have a gothic feel to them. They eccentrically protrude from the beach’s flat surface to form intriguing spikes and archways.
