Using Flash, PhotoShop and PowerPoint, you can produce animations that can explain your research as no static image can. Chapter 3 of Explaining Research covers how to find or develop animations and incorporate them into talks. Here are excellent examples of what is possible:

• Biointeractive animations
• BioVisions
• Cell Size and Scale Illustration, Genetic Science Learning Center, University of Utah
• Eduscapes collection of links to Flash animations
• Exploring Life's Origins, Boston Museum of Science
• How Stuff Works
• Johns Hopkins Institute for NanoBioTechnology
  
• North Harris College Natural Sciences collection of links to science animations
• Red Riding Hood told only through data visualization
  
• SciDAC Best Scientific Visualizations of 2009
