Hovis Presenter is a lightweight and fast alternative to the likes of Powerpoint for running presentations.
It contains no slide creation tools, and only displays images (jpg/png/gif) and video files in the Windows Media Video format.
However it is designed for very fast video start up, usually under a quarter of a second for a standard sized video. This makes it preferable to Powerpoint et al. that can take several seconds to achieve this.
This fast starting of video makes it crucial for presentations where timing is of the essence. It was written to support a stand up comedy routine and timing is very much of the essence there!
Also provides a Presenter UI with the current and next "slides" shown, optionally a script hint as well.
Supports multiple slave presentation machines via a network
