Video: In Daniel Tammet's mind, "9" looms large

I'm very much looking forward to hearing Daniel Tammet speak at the IdeaFestial. As he described in a brief five-question email interview posted earlier this year, his "richly associative" thinking and its landscape of colors and shapes really is not so different after all.

In fact, every time you make a pun or use a metaphor, you're actually thinking in much the same way as a savant.

All-access and individual event passes to meet Daniel and the many other incredible and accomplished people at IdeaFestival 2010 are available now.
