When Sergio García Sánchez, a Spanish comic-book artist, was given the opportunity to fill a whole room in a museum, he turned to his iPad and decided to sketch, in black-and-white, a single day in a bustling city. The result, produced entirely on an iPad, stretches almost a hundred feet long by five feet high, and just opened at the Centro José Guerrero, in Granada, Spain.

Sánchez divided the extensive space into sections, portraying the city through the intertwined lives of six characters whose daily activities range widely: a kindly delivery man makes his daily rounds; a solitary cartoonist never strays far from the drawing desk in her tiny apartment; a taxi driver with a penchant for photography charms his passengers; a kleptomaniac older woman, magpie-like, collects souvenirs from the city to hoard in her home; a musician, in touch with the pulse of the city, begins and ends his day performing; an elderly man revisits earlier moments in his life after receiving a package of old photos from the kindly delivery man. Though the characters seldom interact, we realize that their lives aren’t as different from one another as they seem.
