If you're among the lucky few to already be in possession of a Google Nexus 7, then you'll be pleased to see hear that the Instagram app for Android has been updated to support your new tablet. The latest version 1.1.7 of Instagram for Android is now fully functional on the Jelly Bean tablet, whereas before N7 owners were turned away with a compatibility message. Though the focus of Instagram on a tablet is on viewing, not creating content, you can also use the Nexus 7's 1.2MP front-facing camera to take your own mugshots and filter them to your heart's content.
In addition, the latest update includes the ability to share Instagram'd photos directly to Flickr as part of the sharing menu once you've saved your image. (Unfortunately there's still no native Google+ support right now, though our fingers remain crossed.)
