Okay, someone help me. The article says:<p>&gt; The new version of the Chromecast is launched. I was already in love with the existing version and [its] JavaScript API.<p>I have a Chromecast and I Don&#x27;t Get It. I&#x27;ll be honest, I haven&#x27;t tried searching for cool stuff to do with it. Sometimes I stream Netflix or Youtube from my phone. I found a way to stream MKV videos from my computer using Chrome. But that&#x27;s it, nothing there is cool or revolutionary.<p>So, what&#x27;s some cool stuff I can do with my Chromecast? I recognize there&#x27;s something neat going on here, but it seems so locked down that I can&#x27;t figure out what it is. Can I write arbitrary apps for it somehow? Is there a cool collection of apps that do... something?<p>Help me out. What&#x27;s cool about Chromecast?
