Poetry often goes way beyond just the naked words. Understanding the context around the writer, including background on his or her place and time matters a lot.
In this sense, this amazing iOS app completely changed my understanding of T.S. Eliot and his classic "The Waste of the Land": https://itunes.apple.com/us/app/the-waste-land/id427434046?m...
Highly recommended. It makes it pretty obvious that there is still so much opportunity to do more things with augmented content.
