Our friends at the surrealist thinktank/clothier Imaginary Foundation have an art installation and pop-up store opening Friday night in San Francisco. Titled “The Undivided Mind,” the exhibition features a series of luminous paintings hung on walls chalked with the mathematical secrets of the universe. The opening is Friday, November 19, at 7:30pm, at FIFTY24SF Gallery. RSVP to receive free, limited edition Imaginary Foundation gifts. Imaginary Foundation: The Undivided Mind
