I was going to hold this back a little while as its still in development.
But I myself couldn't wait and I am pretty sure you guys will be impressed too.
I am working on a virtual world, much like club penguin. Users will be able to move around their adopts on the screen on any background and will eventually have supported chat bubbles.
What I have right now is just a single player demo so you can just click and move the adopt. still pretty cool though.
Here is the demo

This is being programed in Java. So you will need a java plugin on your browser and enable it. Also there will be a security prompt, go ahead and click run. I promise you the code is nothing more than a game that listens for mouse clicks then moves and animates the adoptable to it. :)
