Google has recently announced the launch of Google Swiffy which is a free to use web application for converting SWF files into HTML5.

It supports many common SWF features such as vector graphics, embedded fonts, images, timeline animation and basic ActionScript 2.0.

The output works only in WebKit browsers as it includes some SVG features that are not supported by other browsers.

The usage is very simple: just upload the SWF file and Swiffy will display the HTML5 result where you can "save as" the page and insert into any website with an <iframe> tag.

P.S. The code generated by Swiffy is pretty complex and hard to edit. You'll still need the .FLA file for editing the source.

leanModal is a lightweight jQuery plugin for displaying modal boxes with minimum effort.

The plugin doesn't use any images and a very good solution for for displaying anything except image galleries as there is no built-in support for that. But that's ok considering it only weights 780 bytes (when minified).

The width and height of the modal box is flexible and adjusts itself according to the content.

Multiple instances can be used on the same page and there are almost no settings or complicated usage instructions which is perfect for most cases.
