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.

I created a prototype of the UBER app for Android in order to demonstrate what is possible using Proto.io. This project was a massive undertaking as my goal was to simulate the user experience of what it would be like to order 4 different UBER cars in San Francisco. I plan on doing a full "behind the scenes" article on my website about the challenges I faced along the way simulating the UBER app in Proto.io. Special thanks to the awesome team at Proto.io for all of their tireless assistance along the way!
