In "Tributes to the Datastream",  two art photographers have been following peoples' Twitter feeds and then going to the locations where some of them were sent from, capturing an image, and matching the tweet with it.

Imagine if you were able to simply write a product question on a print advertisement and have that message immediately sent to a company? How about writing "buy" on a print ad and having your computer/pen find that item on Amazon.com? This fascinating technology is actually being developed, and has several other handy applications as well.
