Applications for Education
Creating videos with Flixtime could be a good alternative to slideshow presentations. In the past I've had students use Animoto to create videos as mini-biographies of famous people in US History. I've found that assignment to be a good way to get some of my special education students interested historical figures. The students start out by looking for images and reading image captions before progressing to more in-depth reading. The same type of project could be done with Flixtime.

Update: After Mr. Wylie corrected my comment about Animoto's editing options, I edited this post to more accurately reflect my initial impressions of Flixtime.
