Need to make a quick Slideshow with images, or work on one collaboratively?

Try out It’s an open source, completely free, option to make it easy for you to build and collaborate on presentations.

It’s abit limited right now, as there’s no designer included yet, but from their site, it sounds like they may add one at some point. You can upload images of any pages you make with a designer, so it has possibilities.

It’s worth a look, and hopefully a project that will grow over time.
