This is the official description:
Turn your TV into an Instagram Viewer. InstaGallery retrieves popular images and videos and plays them like a slideshow.
Sit back, relax, and enjoy the show.
This is the initial release. Look for a lot more to come.
**This product uses the Instagram API but is not endorsed or certified by Instagram.**

The most important part is: This is the initial release. Look for a lot more to come.
The ability to sign in, see your feed, follow users, and make playlists will be added over time.

I am excited about the media viewing capabilities on OUYA.
I'm looking forward to getting Facebook photos and videos in an app, too.

What do you think?
