Adobe Edge preview is an upcoming tool for creating smooth motion and transitions for screens of all sizes, utilizing the latest web standards like HTML/HTML5, JavaScript and CSS. Highlights include:

• Visually create motion content in an easy to use, timeline-based interface
• Create new compositions from scratch, import and energize web graphics, or add motion to existing CSS-based HTML layouts.
• Trust that your content works reliably on desktops as well as devices.

I’ve downloaded the prototype so I can play with it so I’ll most likely be posting whatever I come up with soon.
