Prezi

Prezi is a cloud-based presentation authoring software that can be created and edited online on the Prezi website or offline on the client side.Prezi uses a storyboard format that allows presenters to zoom in and out of images and demonstrate key points through quick animations.

In addition to panning and zooming, Prezi also supports the embedding of various media materials such as images, videos, PDFs, etc., which can be edited by multiple people online, and the generated presentations can be viewed locally, uploaded to a server or embedded in a web page for online viewing.
