PreZen is a PowerPoint-like code library that allows one to code up a presentation rather than drag and drop it. Its main use is to allow one to code up presentations and use them inside a browser rather than download a PowerPoint and load it. Since this is built on JavaScript, it will load on most modern browsers.
If the content is relatively placed, it can scale up and down correctly.
In addition, the library itself has hooks if reading the mouse input is not a viable option. Jwerty is used to read in user input so it can also be controlled directly via the keyboard.
Included is a sample slide that I have used for my presentation in my Electrical Engineering Colloquium Class, as of 04-28-2013.
Created by unsignedzero and started on 01-25-2013 as an idea.
