This is a really powerfull solution for alternative form of presentations.
The timeline approach transmits a narrative flow to the presentation and the power of hyperlinks to show videos, images, audio is a big addition.
This is one complementary alternative to Prezi.
You give the user the power to control the flow and the hyperlink is something tha Prezi lacks. These two tools offer a new way to present content in a rich and engaging style.
I can advise it.
