TED, if you've not found it yet, is an organisation dedicated to encourage us all to think. They hold conferences and shows and invite a staggeringly diverse range of people to deliver short 20 minute talks on their area of expertise.

TED offered their talks to the BBC and they turned them down as being 'too intellectual'.
