I first "met" Dr. Rosling when I watched his famous TED talk on statistics of development indicators: And then today, I came across another video, where he uses lego to demonstrate the distribution of population growth: Enjoy, and thanks Dr. Rosling :) Follow him on Twitter here .

Some changes: - Simplified, minimalist design - Summarized purpose - Embedded youtube video of latest mix on homepage In the works: - Hosting a music stream to be broadcast - Embedding audio samplers within website (instead of youtube links) - More consistency between homepage and social networks (Twitter, Grooveshark, etc)

I got sent this article today (thanks, Aly) about how seeing the letter "A" before a test produced better results from students than seeing an "F". An extract: " We believe that the meanings inherent in the evaluative letters were enough to influence their performance through the motivational state that they produced. Exposure to the letter A made the students non-consciously approach the task with the aim to succeed, while exposure to letter F made the students non-consciously want to avoid failure. Research suggests that when people approach tasks with the desire to succeed they perform better than when striving to avoid failure. " Read the original article by ScienceDaily here .
