Glider is a presentation system which lets the audience interact with the presentation, chat and ask questions of the presenter. Instead of submitting to a linear presentation, the audience can vote on what slides come next, comment on slides and vote on each others questions so only the best get asked at the end.

Glider is open source, GPLv3 because some bits are patent-pending to open a debate on software patents. The GPLv3 ensures all patent rights (if any) come with the software, along with copyrights etc.

Glider is written in ruby on rails and is experimental at this stage.
