Showoff is a slideshow presentation tool with a twist. It runs as a web application, with audience interactivity features. This means that your audience can follow along in their own browsers, can download supplemental materials, can participate in quizzes or polls, post questions for the presenter, etc. By default, their slideshows will synchronize with the presenter, but they can switch to self-navigation mode.
Showoff allows you to author your presentation slides in Markdown, then organize
them with a
showoff.json file. This file also contains metadata about
the presentation, such as the title, any password protection, etc.
Then you just run
showoff serve in the presentation directory and open
a browser window.
Beyond the standard presentation functionality, Showoff provides:
Live presenter tools:
Live audience tools:
Content creation and distribution functionality:
Due to it being plain text, you can easily version control it, you can easily move sections between presentations, and you can rearrange or remove sections easily.
Showoff is distributed as a RubyGem. Simply install it like any other gem. Showoff will run out of the box on OS X and most Linux distributions. To install on Windows, you'll need to install both Ruby and the Ruby DevKit for compiling native extensions.
gem install showoff
Please see the user manual on the Showoff homepage for further information.
