Path App Fly-out Menu using CSS3 & jQuery

I am a huge sucker for great ui design so I fell in love. The thing that really stole my focus was the awesome fly-out menu that is in the bottom left corner. This button is the main means of navigation in this app. It had not only some good features but also had smooth animations as well. Me being a noob to application development, googled if it was made in phone gap due to it heavy customization and no it wasn’t. It ‘apparenly’ has too advanced animations.
