John Baldessari, working with the LA-based e-newsletter ForYourArt, created an app called In Still Life for the iPhone that allows you to rearrange the composition of the 1667 painting Banquet Still Life. The exercise is based on a similar interactive piece Baldessari made for a 2001 show at LACMA and makes you realize how many objects are squirreled away in old masters paintings (10-points if you can find the mouse in my version above). The app is accessible online at http://in-still-life.com
