With the release of the new The Da Vinci Code movie, the interest in Dan Brown’s novel of the same title is simply phenomenal.
As another nice example of what is possible with Web 2.0, some creative minds has actually created a Da Vinci Tour and Da Vinci Code Map, both based on Google Maps. This is what is known as a mashup (of Web 2.0 technologies, that is) in Geek-speak. This means from now on you can actually navigate to all the key locations mentioned in the novel. Cool!
ps. For more examples of mashups using Google Map, there is always the Google Maps Mania.
