Empressr

Empressr is a great presentation site. It works like a PowerPoint but there are more options for creating your presentation. You can easily add music and create animated slide transitions. You can also upload photos and video. It is easy to move around all of the elements that you need to create an impressive presentation.

The example above is a PSA that a university professor created. Empressr presentations would be great for classroom projects in any subject. The site requires an account to save. Each student can create an account or you can create one account for your class.
