Tap/Hold the black circle to see the 2 state animation of the Keezy sound looping app. A circle of circular buttons spins out onto the expanded black circle that becomes the screen background. Once you're on this 2nd state, tap anywhere to return to the initial state. I recorded a webinar showing how to create this interactive animation: http://docs.proto.io/videos/re-creating-bespoke-interactive-animations-with-proto-io-2/ You can also find the assets here used for the prototype. Enjoy!

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.
