I just experimented the two new features of Instagram. They are the Boomerang and Layout.
Boomerang is about shooting a burst of photo(up to 20 frames) which are then combined into a creative video that plays forward and backward – sort of like an animated GIF. The video is saved in the camera roll, and you can select either the Instagram or Facebook button to post.
With Layout, you can create a collage of multiple photos into one. You can easily reposition the photos and resize the boxes.
Here is one example of Layout.
