Recently I was surfing and found one very stylish menu built in flash. It was just awesome.
I have analyzed it for some time and found that this can also be done with java script also. Actually I am big fan of mootools so I have picked that for this task and you can see the result at the demo page.
Only used mootools tween effect to make this work. Obviously there is a bit of css involved in this.
In css part all the things done by background-position.
Hope you like this. Here is the demo for the menu. Demo
