Mozilla launches Popcorn Maker, a Web-based remix tool
Based on the Popcorn.js library, Popcorn Maker allows users to pull web-based elements like video, text, images and maps into a timeline. This is an early version of the Popcorn Maker but it is promising because it uses open standards like CSS and HTML 5, is free to use and is browser-based. This sets it apart from proprietary tools such as Flash.
You can remix the Radio Rookies’ piece here to get a sense of how Popcorn Maker works.
