This project is inspired by Vasjen Katro’s concept ‘Clubbing & Nightlife’ App ‘2Night’. It showcases how Proto.io can be used to create a beautiful parallax scrolling effect. If you’d like to find out how I achieved this effect feel free to import the project into your own account for reverse engineering. https://dribbble.com/shots/2041810-City-intro-animation

The recently released Google Inbox app is a re-thinking of the email inbox experience that beautifully demonstrates Google's material design interactive animation language. This prototype focuses on the compose button's animation. Click the + to reveal a new state where a wave of buttons and labels float up, and the + becomes a pencil icon. It uses two states, with staggered animations.
