Presentz is a javascript library for synchronizing videos and slides, so to reproduce conference talks as faithfully as possible.

It's a mashup, as it merges things like Vimeo, Youtube, Blip.tv and Slideshare together. But you can use raw images, swf and video files as well, unleashing the HTML5 video tag power.

Presentz is a work-in-progress.

You can drop an email and ask questions, take a look at the demo talks or enjoy the JUG Torino, the 8th Italian Agile Day and the Codemotion 2012 talks catalog.
