Although the Smithsonian offers free admission every day, many museums aren’t able to do so. Therefore, the Museum Day Live! idea was born.
Now, identifying a tree is as easy as taking a picture of a leaf. A new app for iPad and iPhone called LeafSnap will search a massive library of leaf images from the Smithsonian Institute and in seconds will return a likely match with just about anything you'd ever want to know about the tree in question.
