Two days ago I posted about a motion graphics video that was designed beautifully but relied too much on text bullet points to compare quantitative data, the brain had to do too much work in too little time (before the next piece of information shows up):
  1. Read sentence
  2. "Visualize" numbers internally
  3. Interpret them
This is a better example of the use of motion graphics. Zooming is used to visualize the enormity of the number 1 trillion. It comes at a price though: this video is almost a full-blown animation. A bit of PowerPoint/PhotoShop skills and After Effects are not enough to produce it (unfortunately).
