Sozi is a piece of software for creating animated presentations. It is generally used to make visual aids for lectures or meetings. With Sozi, a presentation is not organized as a sequence of slides, but rather as a succession of viewpoints on a map that you explore.
Sozi is quite versatile. Some creators have already used it for other purposes, for example to make animated infographics, websites, or interactive fiction.
I have been developing it since 2009 and I think it has become a nice and fun tool to use, but not always easy.
