Moobile is a new mobile application framework built on MooTools.
Currently, it is focused on providing a iOS-like experience on WebKit browsers and comes with many controls like bar, button, image, list, activity indicator, slider and more.
It also has support for transitions like fade, slide, cubic or cover and can display native-like alerts.
Interfaces created with Moobile are fluid, they will work well both in iPhone + iPad and look good when orientation changes.
The download package includes a boilerplate for quickly starting projects, related PSD files and a simulator.
