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.
Arx Libertatis is a cross-platform, open source port of Arx Fatalis, a 2002 first-person role-playing game developed by Arkane Studios. Arx Fatalis features crafting, melee and ranged combat, and a unique casting system where the player draws runes in real time to effect the desired spell. The Arx Libertatis source code is based on the publicly released Arx Fatalis sources. This does however not include the game data, so you need to obtain a copy of the original Arx Fatalis or its demo.
