Tumblr has a very nice series of animations that happens when you enter the compose mode. I thought it would be interesting to recreate this in Proto.io to show others how to achieve these kind of effect in their own protototypes. I have made a companion tutorial video where you can see exactly how I did it. This video is available here: http://docs.proto.io/videos/recreating-tumblr-compose-animations-in-proto-io/
