As a Prezi lover, I keep an eye on what is going on with the tool. And just today I have discovered that a 3D Prezi option was added to the templates.
When you just start your new Prezi and are given a list of templates to choose from, you can easily see the 3D options as they are all labeled '3D' in the bottom right hand-side corner.
There is also a more advanced 3D option available where you can upload a background image from your computer which will then be turned into 3D. You can also add up to three background layers with a 3D option to your Prezi via the Theme Wizard.
I created this short presentation with a 3D template available on Prezi just to see how it looks. I have to say, I really liked what I saw. I hope you like it too.
