Sliderocket is a new presentation tool! As a district who uses Google Apps for Education, we are able to use it for free (it is now under "more"). They do offer a "Lite" version that is free with some basics available. The paid versions offer analytics and more advanced features. The ease of using this makes it even more appealing! Have a lot of PowerPoints or Google Presentations that you already use?....no problem, you can upload them into Sliderocket. You really need to explore it to see all of the great possibilities!! Below is a sample of one I created - and had fun doing so!
