Ground Zero for Mobiles: how it works
Have you ever wondered what would happen if a nuclear bomb goes off in your city? With Google's Maps framework and a bit of Javascript, you can see the outcome. And it doesn't look good.
This version of our popular "Ground Zero" application is geared for mobile devices. It has been tested on an iPhone 4, an Android G1, an Android Nexus 1 and a Samsung Galaxy Tab.

Technical Stuff: about GZ for mobiles
1) A reasonable app for mobiles must cater for screens of a smaller size and resolution.
Fortunately for us, we have a brand new tool: media queries, defined in the forthcoming W3C HTML5 standard.
In a nutshell, CSS3 media queries adjust the style of your website to the screen being used, by selecting different stylesheet files. Powerful stuff. Older browsers might have problems here, and may not load the CSS files.
Even better news: the Mootools library is used to recalculate the screen layout. CSS media queries are still in very early days.
2) The Google Maps API was updated to version 3 -there is work here updating code and testing functionality, but it's worth it. Faster, leaner, meaner. Just what you need for a 3G mobile connection.
3) Removed jQuery and replaced with Mootools. There are some good reasons behind this change -we like both libraries, but at this moment Mootools seems more suited to the task.
4) GZ for Mobiles uses Geolocation services to place your current location as "Ground Zero".
Older browsers might have problems here, but this app was designed for modern, WebKit based machines. It is not a universal application and support for IE has been disabled.
You must allow GZ to use your current location - just click on the appropriate button the first time you launch the application.
