Jorge Colombo drew this week’s cover using Brushes, an application for the iPhone, while standing for an hour outside Madame Tussaud’s Wax Museum in Times Square. “I got a phone in the beginning of February, and I immediately got the program so I could entertain myself,” says Colombo, who first published his drawings in The New Yorker in 1994. Colombo has been drawing since he was seven, but he discovered an advantage of digital drawing on a nighttime drive to Vermont. “Before, unless I had a flashlight or a miner’s hat, I could not draw in the dark.” (When the sun is up, it’s a bit harder, “because of the glare on the phone,” he says.) It also allows him to draw without being noticed; most pedestrians assume he’s checking his e-mail. – from New Yorker
