I started looking for alternative presentation tools for one of my always traveling friends and found Zoho Show . It is completely free for personal use, presenters can access their presentations from anywhere. You can export your slideshow to PowerPoint if needed, share your presentation online and track how many people have viewed it.
Presentation sharing site Slideshare is growing in popularity, users can upload Word documents, text files, Excel spreadsheets, PowerPoint presentations, PDF files as well as files created with Open Office (odt) and access them from the Slideshare site when presenting. There is a 100 MB maximum allowed upload file size limit.
OpenOffice 3 Impress is a free software for creating effective multimedia presentations. You can use 2D and 3D clip art, special effects, animation, and high-impact drawing tools. It is possible to save your slideshow as a PowerPoint file.
Google Presentations belong to the Google Docs and Spreadsheets family. One advantage that Google Presentations has over PowerPoint is the fact that all steps – the presentation creation, development, viewing and sharing can take place online.
Sliderocket is another emerging web-based tool. Users can incorporate video and publish their presentations online or embed them on their websites. Their free plan provides 250 MB of storage.
And yes, you have to learn presentation design from Garr Reynolds.
Spice up your presentations, spread your ideas!
