This is a free tool for making slideshow presentations. OpenOffice Impress enables you to create slideshows with different elements starting with text, images and shapes, and to animate presentations and include media like sound and videos in your slides. It’s very easy to start using Impress and if you have used Microsoft Powerpoint before you will find it even easier.
Because it is part of the OpenOffice suite, it's easy to include things you have created in other OpenOffice tools. For example, if you create charts and tables in OpenOffice's Spreadsheet - Calc, you can embed these directly in a presentation made in Impress. When importing and exporting documents from PowerPoint into Impress, some things might not work straight away. This can affect animations, slide transitions, headers and footers, date and number fields as well as colour schemes.
