Aspose.Slides for Java is a Java component for manipulating PowerPoint presentations. It doesn't require PowerPoint and supports export to PDF, embedding and linking of audio and video frames, slide cloning, thumbnail generation, and presentation features, the ability to extract text from a presentation, and more.
PRISCILA is a simple SDL/OpenGL presentation application with a keyboard-based WYSIWYG built-in editor. Its aim is to provide a vi-like tool to write presentations. The current editor is still very rudimentary and several editing actions have to be done by editing text files. Each presentation slide is a real 3D scene composed of several items. Special effects can be applied to modify item appearance, and actions can be added to modify items' behavior. 3D objects, effects, and actions are GNU/EDMA objects, which automatically provides plug-in support, easy updates, and more. An RFComm Bluetooth interface is included for remotely controlling a presentation from a mobile device.
Presentation is a standards-based presentation platform in the style of S5 and Opera Show Format (both of whose file formats are supported). It provides an easy way of writing (in HTML or XHTML) a portable presentation that can easily be read from a standard Web browser. In addition to what was offered by S5, it adds support for CSS3 transitions.
picoFlamingo is a portable presentation solution initially developed for the BeagleBoard and picoDLP projector, but it can be executed in any OpenGL ES 2.0 compliant system. The project can be considered a reduced version of Priscila, a GNU/Linux based presentation system that defines the presentation slides in a 3D space. Slides can contain text, images, live video streams, and 3D objects that can be animated in a 3D space and dynamically updated to produce advanced user interfaces. When used in combination with NetKitty, picoFlamingo can be controlled remotely through any Bluetooth or network enabled device. Simple remote control tools for Symbian S60, OpenMoko, and Android 1.5 are provided. A set of small applications for video streams and voice commanding are also provided.
Encours.org is a teleconferencing system that works directly in your Web browser. It has shared slides that are visible to all, an integrated audio system with recording, "laser" pointers for lecturers, video replays of the presentation, and a chat interface with the audience. It can be connected to a phone server.
