Online sites for creating videos so no software is needed. I have used WeVideo, which has gotten better apparently since I last tested it last month. Use Animoto regularly, but need to watch the pacing and slow down the videos. Zimmer Twins is fun site. Need to play with it more. Have used Screenr and other screencast tools, but Screenr is one I abandoned in favor of other options. More options for using online sites to create videos continue to pop up.
