Twitch.tv Widget
Update!
This has become Streambadge.com, a service I created and released to the wild in March, 2014.
Twitch.tv Widget is a simple widget to check to see if a user is streaming on Twitch.tv. If true, the widget displays the game name and viewer count.
Example
Usage
Add to your web site or blog like so:
<iframe src="http://svinkle.github.com/twitch-tv-widget/?username=[YOUR USERNAME]" width="100%" height="64" frameborder="0"></iframe>
