Rachel Harrison’s “Caution Kneeling Bus” premieres for the U.S. a series of paintings made with the help of the smartphone app Scanner Pro. Open at Regen Projects until February 20, these works began by utilizing the software’s function for a different purpose, scanning various spaces and objects as opposed to its intended purpose to recognize and digitize text. The resulting images are filled with glitches, disorienting views of gravity defiance, and splotches of color and shapes, which the artist then finishes with the addition of paint. Alongside these painted prints, viewers will find a suite of sculptural works utilizing everyday materials like styrofoam, chicken wire, cement, and cardboard, like the orange-and-blue Paint Can or a storage cabinet labeled “flammable” with a form perched on top, titled Slimline.
