And when it comes to information designa recent infographic from XPLANE does a nice job of graphically representing the complex idea of how Obama has reinvented campaign finance by leveraging the power of online social networks. And this post by Ewan McIntosh is one of the best explanations of what makes for a good presentation.
When we experience a presentation we experience it in two ways - through the auditory nerves (ears) and the optical nerves (eyes). The brain is geared up to seeing above all else: 30% of the cortex is devoted to visual processing, only 8% for touch and 3% for hearing. So, biology tells us that our presentations must be, above all, visual.
Another quote I like: "PowerPoint doesn't kill presentations, bullet points do."
