Prezi
This is prezi, the next generation of power point. I like to use this as I can make presentations that look more crisp than PowerPoint and adds a whole new dimension into presentation. I am not sure I would use this as I am currently working with Brian "Squirrel" Eiserloh who has worked on Call of Duty, Battlefield, and Doom to create a new computer OS with its own node ("atom") based 3D presentation system which allows you to upload a photo which is then sliced into layers which are expanded from each other to create a 3D elusion, and if you have 8 pictures of the object of the photo from each angle you can move around it while it is fully 3D. This system is hard to develop as we have no graphic designer though and a computer program which predicts an objects shape is difficult to make.
