A game running in your browser's address bar

Edit: Oh no, the back button was grayed out. I thought it affected nothing to my history. My thought is wrong. Completely wrong.
It has quite a few features, and it groups visits by site untill you expand it. I easily deleted it all in one button click.
I really wouldn't be able to think of any off the top of my head...
That used to be what the status bar was for, until scripts started modifying it to hide link destinations (onclick= etc.) so that ability was disabled for "security reasons". Now the status bar is gone completely from most browsers by default, but onclick= can still be used to obfuscate link destinations.
Also, status bar scrollers were rather common on the "old web"; they won't be missed, and I hope address bar scrollers don't start being the next "cool thing". It's a fun demo-effect, just not something I'd like to see all the time.
But in brief, it's a fairly simple case of using JS to set "window.location.hash" to whatever value necessary. If you want to test this out, you can open your browser's JS console (on any website), and simply type something like this:
window.location.hash="test"
and it'll update the URL displayed in your navigation bar.Then it's just a case of using some JS code to generate the text to place in the navigation bar. It's quite a neat idea, but it's also pretty simple.
