Travel time visualizer

Some more playing around with the google maps API...

It's a little complicated to explain...

The user defines a center point of interest, then a surrounding search box.

Javascript then divides the search box into a 20x20 grid and runs google maps directions queries to work out estimated travel time to each point. The times are then plotted using an intensity colour map. Unfortunately due to the nature of the google maps API this is only an academic exercise as the plots take an hour or so to create.

Potential uses could be for would-be house buyers to see what things are in a given travel-time radius.

For example. Search grid over London and surrounding area.

Another example, Sheffield.
