Apture

This service is a really impressive, innovative way to enhance your website/blog/etc to add contextual, overlaid "buckets" of media, links, and news wherever you want on your site. It integrates well with an open source CMS like Drupal (we're tried it a bit here on newmediarights.org) or open source blog software like wordpress . Simply make sure the small bit of embed code shows up on any pages you want to use it, then customize your contextual frameworks or "bucket" using an overlay in your browser. Perhaps most impressively uses pop-ups without being annoying.

From the site:

Apture provides the first rich communication platform that allows people to intuitively experience the web.

With just one line of code, publishers and bloggers can quickly and easily turn flat pages of text into a compelling multimedia experience. Apture gives content creators the power to find and incorporate relevant multimedia items directly into their pages. Readers can then access these items without ever leaving the page, providing them with a deeper and more meaningful web experience.
