TimeJump is a JavaScript library which adds deep linking capabilities to your HTML5 audio/video podcasts.

TimeJump works just like YouTube time linking with #t=. Basically, with this library you can link separate sections in your video/audio podcasts, but it’d work for songs as well.

It’s already being used by a number of well-known podcasts, such as ShopTalk, BookBytes, The Changelog and others.

Stratus 2 is a jQuery-powered SoundCloud player that lives at the bottom/top of your page.

Stratus can be installed on WordPress, Tumblr and Blogger websites. It has a number of useful options together with a neat ‘random’ option (never seen that one in such plugins).

Stratus is used in a handful of websites already, and this speaks for itself.

Photobooth.js is a standalone plugin that allows taking pictures with the users’ webcams.

The plugin can be used standalone or with jQuery, the latter way being easier for the code, the first way allowing you to bar jQuery from your app.

You can specify the width/height of the “photo booth” and Photobooth even has a property for checking if the browser supports fetching media from the web cam.

Browser support is scarce though: IE and Safari aren’t invited to the party.

Joy Divisor is an HTML5 experiment by @eddietree that visualizes sound waves in a manner not unlike Joy Division’s iconic album cover for their debut album, Unknown Pleasures.

Joy Divisor fetches music from SoundCloud usings its API, and requires several libraries, such as jQuery  for functioning. It seems that the experiment is quite performance-demanding, but that’s beyond the point I guess.

Tampon is an easy-to-use tweet scheduler app good for corporate and mogul twitter accounts.

While tweet scheduling takes away from the spontaneous nature of Twitter, some people just can’t afford to waste their time on it.

At any rate, Tampon runs on Backbone.js and MongoDB.

Tweets can be re-ordered with drag&drop functionality, or posted instantly.

Allofthelights.js is a jQuery plugin for darkening the screen outside a video. 

The plugin works responsively and on most modern browsers (IE7+). It also has controls like adjusting the background color and opacity.  FitVids is used for resizing the videos.

What I would like to see is an implementation of full-screen with this plugin, as the desktop doesn’t get darkened.

However, that would probably present quite a number of problems.
