Calculate the distance between two zip codes

A fun little online application that calculates the distance between two zip codes. The distance is calculated and general information about each zip code, a map for each zip code and approximate driving time is displayed.

Why?

Like most stuff I do its practice. This one was practicing with Zip Codes and calculating zip codes that may fall within a certain radius of others. The best way for me to practice is to make something and usually after its made I create a website out of it in case others find some use.
