Websites My first AJAX implemetation

Hi,

I started to learn AJAX,
and as part of my learning decided to use it in my site.

Because I own a game site,
I added refresh button for random games,
so when you click it the random games are refreshed.
Cool way to choose your games this way

Please give me your feedback about it (it is the refresh icon on top left of the screen):
My refresh button

Thanks!
