Some benefits to SlideCasts:

• Let you add your own voice narration to your PowerPoint presentations.
• Support your builds and animations.
• Let you share your presentation with others securely (so that no one else can modify or copy your slides).
• Enable users view and listen at their own speed.
• They’re free to build and view.
• Must be a NanoScienceWorks.org member

YES. I'd like to produce a NanoScienceWorks.org Slidecast. Contact me.
