jQuery and Browser based games

Surfs Up!
I have been playing with the jQuery animate functionality a bit today and it occurred to me that jQuery would likely be the perfect library to build a browser based game on top of..
I did a little browsing about the web, and sure enough.. someone thought of it before me.
The games I would want to create would be less animated than this one.. but I could totally see a Masters of Orion remake as a browser based game using the jQuery library.. Or any number of other turn based games.. You could even make them multiplayer fairly easily..
As computers get faster, and as browser trend towards threaded javascript engines.. Why the hell not?! At this point I think it would be just as easy/difficult to create a game via a webbrowser as it would via any other medium..
