Need to sketch but don't want to carry around your bulky sketchpad? You're in luck. As the well-known advertisement would state: "There's an app for that." This week's cover of the New Yorker is a true first in magazine cover art -- the entire image was created on an iPhone. Artist Jorge Colombo drew this cover design using the iPhone app Brushes. What next? Will museums begin displaying works of "fine art" created on iPhones? Yikes.
