This is a TED talk by Steven Johnson on the origin of great ideas.
(1) stimulants (like tea or coffee) are better than depressants (like beer or wine)
(2) consulting with lots of people is a good thing - connections lead to innovations. Periodic reviews with the team are important - the process of sharing problems and results of current work leads to new, possibly useful juxtapositions.
(3) chaotic environments = collisions between ideas and concepts. "Chance favours the connected mind".
