[Foreword: if there's already a thread for this, just tell me and I'll get involved there and delete this one]

People seemed to like hearing Trace Mayer on BBC Newsnight last week - mainly it seems because he was clear, well-informed and came across as a intelligent and eloquent advocate for Bitcoin.
There aren't enough people like him out there, and I also don't think there is enough access to clear material that explains the benefits of Bitcoin to the average person.
So, I want to put together a list here of animations / infographics / YouTube videos / data visualisations that do well in this area.

I also want to put together some animations myself to do my bit to help with promotion and education - if anyone's interested in collaborating please PM me.

I'll update the list at the top of this thread. Here's the kind of thing I'm talking about:

What is Bitcoin? (weusecoins.com) - YouTube Video https://www.youtube.com/watch?feature=player_embedded&v=Um63OQz3bjo
How a Bitcoin Transaction Works - Infographic (http://spectrum.ieee.org/img/06Bitcoin-1338412974774.jpg)
