When going to look at famous masterpieces, you have to deal with jostling museum crowds and sometimes overzealous guards shooing you away if you get too close. Not to mention traveling to Florence or Paris or St. Petersburg or wherever. But now, thanks to yet another happy by-product of the Internet age, Leonardo Da Vinci’s The Last Supper is available as a special digital image that lets you get (virtually) closer to its surface than you ever could in real life. (Real life in this instance being a church in Milan where reservations sell out months in advance.)

Officials in Milan worked with the wittily named Italian company HAL9000 to put a 16 billion–pixel digital image of the painting online — which basically means you can see high-resolution details of sections as small as a one-millimeter square. Thanks to the easy interface, you’ll soon be zooming and panning over the image like the world’s most privileged art historian.
