I like non-linear presentation software like prezi. The problem with Prezi is it is not open source and not a desktop client (For linux). You will say use Libra-Office Impress but it is linear and I hate that. If there isn't any non-linear presentation software for linux like Prezi Desktop, than is there a plugin that make Libra-Office Impress like it or Apache OpenOffice? I want a desktop client, and not a web-base app!

[1] Linear Presentations are those presentations in which the flow of the presentation is controlled by the person who is presenting. The concept is frequently employed in multimedia applications and presentations. An example of linear presentation is a pre-recorded movie presentation.
