The Lily team have already built in over 180 externals objects:
- web service modules for APIs like Twitter, Amazon, Flickr, Wikipedia, Yahoo;
- UI modules that wrap web components from YUI, JQuery and Google Maps as well as the browser's built-in UI elements;
- modules that offer access to the network, SQLite storage, TCP sockets or the file system; modules to interact with the browser;
- modules to send and receive Open Sound Control messages or talk to the Arduino physical computing board;
- and, graphics modules that encapsulate the browser's SVG functionality and multimedia modules for playing sound and video.
Now it's possible to use a browser-based program to make web or desktop mashups, allowing people with basic skills to visualize and animate data, modify webpages, play music, or connect to world outside the computer.
Another neat aspect is that your programs can be shared with other Lily users as text files or they can be run by anyone as Firefox add-ons or standalone XULrunner applications.
Lily is free and open source, released under the MIT license. Lily runs on Mac, Windows or Linux, just like Firefox.
