My phone does AJAX

I think I can make a nifty game using just text, Javascript, and XMLHttpRequest. And, since this page halfway works on my phone (but not at all in IE, of course), I could then play it on the phone.

This is not even remotely the project I am working on though. So no matter how neat this would be, I must resist the urge to abandon what I'm making half-finished and make this instead.
