I would like to let you know about our newest creation that, in our opinion, may revolutionize the way presentations are conducted - MindShow for iPad. Our aim was to address the problem of linearity of the presentations imposed by the available software. Applications like PowerPoint or Keynote force the presenters to follow 1-by-1 slide pattern, making them unable to e.g. easily address questions from the audience.
The idea behind MindShow is to use mind-maps as a more natural way of delivering visual presentations. In this respect presenters can always create various paths for a given presentation and be prepared for every scenario. Furthermore, they can seamlessly add new slides or images to an on-going slideshow, staying agile and flexible.
Take a look at the videos and the screenshots:

If you want to give it a try first, there's always a lite version:

If you have any questions or comments, I will be more than happy to answer them.
