Here is a story: for a one customer of mine I created a simple site with contest – visitors can register and got chance to win a notebook (http://thinkpadedge.cz/soutez/ – but this is not important) … after a while I was asked if I can quickly (I’ve got a night for it) develop a tiny application which draw a winners – specifications were simple:

Create an application with installer for Microsoft Windows which from the given range draw a specified count of numbers (IDs in the database of original site). Drawen numbers should be easilly copied to the clipboard or saved as a plain text file.

Solution: XulRunner-based application with installer created using Inno Setup.

Result: Application was created in less then three hours (and significant amount of time was spent with icons) and customer was fully satisfied :) .

Here are screenshots of the application:

I hope that this show to all of you the advantages of XulRunner and using of it :)
