Are you looking for a way to jazz up your publisher created PowerPoint slides? Why not Prezify them using Prezi's new PowerPoint feature? You can quickly and easily adapt those static slides into an aesthetically engaging and interactively pleasing presentation using the tutorial and guides found here.
And, if you are really looking to add more value to these slides, you can go one step further by then using Jing or Screencast-o-Matic (I recommend Screencast-o-Matic as there may be some user access changes to Jing in the near future) to record an audio screencast as you go through and guide students through your Prezi PowerPoint.
Give it a try and let me know what you think!!!
