One of the most amazing things you can do with Wolfram Alpha is ask it what planes are overhead. If you're on your phone, it will pull your location, then cross reference that with a database of flights, including their altitude, angle, and even their flight number and aircraft type. But in many ways, Stephen Wolfram's latest search tool is more impressive. It's designed to identify anything in a picture. You just upload a photo, and get a computer-generated guess just a few seconds later.
