It's incomplete (there are features I'd love to see on it) and more of a "proof of concept" just to show what can be done with the current round of web technologies we've got behind the scenes here at subsonicradio.com...
In short, it'll show you which streams are up with icons. mouse over the icon to see the number of listeners, current song (both at the time that the page was loaded-- it doesn't update that). Click on one to bring up a HTML5 player (should work in all modern web browsers, desktop or mobile), which displays the stream info, and the currently(ish) playing song.
It might stop working while things are done with it. It might not be here in the future. but for now, feel free to try it out and/or use it all the time.

enjoy!
