I was playing with Instagram UI and I decided to do it also in landscape mode. You know Instagram has not landscape because photos are published in square shape which is not appropriate for landscape.
But what about this? when you use Instagram in landscape, you only see Panorama photos. although you can crop any landscape photo in that specified ratio. It was fun but I hadn't enough time to design every single page. First I wanted to design an interface that works also in landscape, but I decided to do one in Instagram's format.
I haven't searched yet, but I'm sure there are (and there will be) some social apps for sharing panorama (or landscape) photos, but who has the power of Instagram to do the best!?
p.s. I designed everything from scratch, except the icons
