Snook read Dave Shea’s article on CSS Sprites using jQuery to produce animation effects, he felt like playing around with things to see what could be done but accomplish it with a simpler HTML structure (no need for adding superfluous tags) and simpler code, too.
Changing the position of the background image felt to be the best approach to creating the type of effect we’re looking for. Snook has shown us Background-Position plugin and published an article “Using jQuery for Background Image Animations” about how to use it. The script to put this altogether is really straightforward. The animation needs to run when the user moves their mouse over and out of the navigation. The key thing to note is that any animation is stopped before attempting to animate again. This avoids animations queuing up from repeatedly moving the mouse in and out of the element.

TWiki is a flexible, powerful, and easy to use enterprise wiki, enterprise collaboration platform and knowledge management system. It is a Structured Wiki, typically used to run a project development space, a document management system, a knowledge base, or any other groupware tool, on an intranet or on the internet. TWiki looks and feels like a normal Intranet or Internet web site. However it also has a Edit link at the bottom of every topic (web page), everybody can change a topic or add content by just using a browser.
Web content can be created collaboratively by using just a browser. Users without programming skills can create web applications. Developers can extend the functionality of TWiki with Plugins. TWiki fosters information flow within an organization; lets distributed teams work together seamlessly and productively; and eliminates the one-webmaster syndrome of outdated intranet content.
TWiki is GPLed software. The Perl CGI source code, templates and documentation is available for free.
Requirements: Perl CGI Supported Server

CrossSlide is a jQuery plugin that implements in Javascript some common slide-show animations, traditionally only available to the web developer via Adobe Flashâ„¢ or other proprietary plugins. CrossSlide builds upon jQuery’s animation facility, so it is as portable across browsers as jQuery itself.
CrossSlide can do simple Static cross-fade, Slide + cross-fade and Ken Burns effect: panning, zooming and fading to specific points, to guide the eye of the viewer and convey meaning. This kind of effect relies on the browser for positioning, scaling and cropping images, through CSS and the DOM.
However it depends heavily on how the browser and the underlying graphics platform optimize these operations. Compared to native implementations of the same effects, CrossSlide is quite CPU-intensive, but recent hardware handles it without problems.

You’re writing an email to invite a friend to meet at a local San Francisco restaurant that neither of you has been to. You’d like to include a map. Today, this involves the disjointed tasks of message composition on a web-mail service, mapping the address on a map site, searching for reviews on the restaurant on a search engine, and finally copying all links into the message being composed. And you haven’t even really sent a map or useful reviews—only links to them.
Mozilla Labs has announced the launch of Ubiquity. Ubiquity empower users to control the web browser with language-based instructions. (With search, users type what they want to find. With Ubiquity, they type what they want to do.) And it enables on-demand, user-generated mashups with existing open Web APIs. (In other words, allowing everyubone–not just Web developers–to remix the Web so it fits their needs, no matter what page they are on, or what they are doing.)
Ubiquity lets you map and insert maps anywhere; translate on-page; search amazon, google, wikipedia, yahoo, youtube, etc.; digg and twitter; lookup and insert yelp review; get the weather; syntax highlight any code you find; and a lot more. Ubiquity “command list†to see them all.
All of the code underlying the Ubiquity experiment is being released as open source software under the GPL/MPL/LGPL tri-license as well.

Phusion Passenger is an Apache module, which makes deploying Ruby and Ruby on Rails applications on Apache a breeze. It follows the usual Ruby on Rails conventions, such as “Don’t-Repeat-Yourself” and ease of setup, while at the same time providing enough flexibility.
Phusion Passenger is a commercial supported open source product that enables people to deploy their Ruby on Rails applications in an upload-and-go manner, which is very reminiscent of the PHP way of deploying. Also, you can always get community support on Discussion board.
Requirements: Any OS, except Microsoft Windows

Superfish is an enhanced Suckerfish-style menu jQuery plugin that takes an existing pure CSS drop-down menu (so it degrades gracefully without JavaScript) and adds the some nice features as well. The reveal of sub-menu is animated, uses a fade-in by default but can be given a custom object to be used in the first argument of the animate function. The animation speed is also customisable but is set to “normal†by default.
There is a set of callback functions (onInit, onBeforeShow, onShow and onHide) available as well, allowing for further enhancements and functionality to be added without needing to alter the core Superfish code.
Requirements: jQuery v1.1.3.1+

Facelift Image Replacement (or FLIR, pronounced fleer) is an image replacement script that dynamically generates image representations of text on your web page in fonts that otherwise might not be visible to your visitors. It is similar to sIFR which accomplishes this by using a combination of javascript, CSS, and Flash. FLIR generated image will be automatically inserted into your web page via Javascript and visible to all modern browsers. Any element with text can be replaced: from headers (<h1>, <h2>, etc.) to <span> elements and everything in between.
Requirements: Javascript Enabled
