Pachyderm is a web-based rich-media interactive presentation authoring and publishing system that meets most accessibility requirements. It works off of an extensible template system. Pachyderm allows users to upload multimedia (images, audio, video) and publish them online using pre-defined templates or download them for use on their own website, or on a CD or DVD. Version 3 (released June 2014) now also supports iOS and other non-Flash devices using HTML5, and appears to be a major upgrade. Requires Apache HTTP or Tomcat web server installation (WAMP or MAMP is fine).
PachyForge is a community owned and operated Web site designed to improve communications and promote growth within the Pachyderm open source community. The site is intended serve both Pachyderm developers and end-users in sharing ideas and supporting one another. [from the site].
