This is a REAL odometer style javascript counter, where you can actually see the numbers spining. No Flash, it's all css and javascript. It can serve multiple purposes, like a live visit counter or a cashier style counter on a shopping website. Well, anything that involves updating a numeric value dynamically. It can also be used a fixed counter, like the one you can generate with a server script, but of course that isn't nearly as much fun as updating it in real time.
Jawr is a tunable packaging solution for Javascript and CSS which allows for rapid development of resources in separate module files. Developers can work with a large set of split javascript files in development mode, then Jawr bundles all together into one or several files in a configurable way.
By using a tag library, Jawr allows you to use the same, unchanged pages for development and production. Jawr also minifies and compresses the files, resulting in reduced page load times.
