I'm trying to display a full-screen slideshow, but some of the slides will have internet-enabled/interactive content (news, weather, twitter trends). Is there any software package or combination thereof that I may use to do this? Currently, I'm rendering a video from a slideshow program (iPhoto on Mac OS X), and transferring that to my machine & playing it fullscreen with VLC, but that doesn't allow for interactive or dynamic content.
You can use LibreOffice Impress to do that.. This link explains how to have live data in Impress presentations:
Although the article talks about OO Impress, the LibreOffice Impress also works the same way...
