Slider Kit is a thoroughly functional, all-round purpose slideshow plugin.

The Slider Kit has a number of useful functions you can put to use.

Some of them: change the start pos; keyboard nav on/off; transition fx change; building a “tabbed” menu.

It even has an API, and all in just 8kb (minified).

You’ll be particularly pleased that the devs have made a number of skins you can upgrade and outright steal from.

Overall, Slider Kit is an awesome and well-built plugin.

With its small size, you’ll probably use it in many future projects once familiar with its inner workings.

ProcessWire is an abundantly functional, easy to use open-source CMS written in PHP.

Basically, the CMS takes a very structured approach, and is quite similar to Drupal in many aspects.

What you’ll like about ProcessWire:

• Intuitive, easy use, whilst preserving the ability to do more.
• Drupal-style pages (nodes) give you total freedom on how each page acts (great for designers and for added functionality).
• Easy, jQuery-style API.
• Custom fields add increased versatility to the pages.
• Although a ‘jack of all trades’ is usually the ‘master of none’, the modular system of ProcessWire makes the system very versatile, at least matching Drupal in this aspect.

What you won’t like:

• Besides the obvious gains for designers and newer users, ProcessWire doesn’t have that much to offer.
• Not for blogs — an easy to use CMS, but WordPress is still easier, not to mention design templates.

jQuery Terminal Emulator is a plugin for creating command line interpreters with jQuery.

The plugin follows the standard command line design, and would work for testing purposes, and for outlining yet-to-be implemented features.

With the terminal, you can easily implement JSON-RPC services–in fact, it only takes a single line.

JSON-RPC auth is also supported.

Multiple terminals per page are allowed. You can even add keyboard shortcuts. ;)

Moodular is a jQuery carousel/slider, albeit a bit different from other jQuery plugins.

First of all, moodular is really thorough and well-made.

The plugin supports external function calls, easing, changing movement speed/direction, and even has a ‘carousel’  option, hence the carousel in the title.

Images can be rounded, and you can switch between zooming and fading images.

Besides, you can add a shiny reflection to each image. Neat.
