An update to the Chromecast app for iOS will now let you activate a nice screensaver for your TV populated with all sorts of web content. Backdrops can include Google+ photos, curated artwork, news and lifestyle pictures, satellite imagery, and lots more. If you're looking for more information, just crack open the Google app and ask "What's on my Chromecast?" The Chromecast app itself will also have more information on what images are being shown.
The Chromecast app now has a menu where you can freely toggle what kinds of content is shown, including weather. For those of you unfamiliar, Chromecast is an HDMI dongle for your big-screen TV that can stream all sorts of web content when you use your mobile device as a remote control.
How many of you guys are using Chromecast? Is it doing anything for you that Apple TV isn't?
