Where can i find more things like "the Do lectures"?

I recently came across http://www.dolectures.co.uk/ , perhaps on HN (I don't remember..) and found most of them really interesting. I thought they were a very contrasting and interesting group of people and some of them brilliant in there own simple ways.

I was wondering if there were there were some other things similar,talks or writings alike, that have influenced you somehow and affected the way you think about things?
