 [Screenr] (http://www.screenr.com/) , [ActivePresenter Free Edition](http://atomisystems.com/activepresenter/free-edition/) and other screencasting tools allow you to demo apps.
 To mix together clips, you can use youtube video editor http://www.youtube.com/editor or local software like http://www.videolan.org/vlmc/ or http://www.lwks.com/
+You can use graphics for example [storyboards with these free icons](http://dribbble.com/shots/1083617-430-FREE-storyboard-illustrations)
