I haven't finished watching this - but so far Aaron Koenig seems to speak very well and gives a good intro to Bitcoin.
Aaron Koenig - An Introduction to Bitfilm and Bitcoin
Aaron Koenig gives a talk on the creation and use of Bitcoin, a new digital currency, and on a payment system designed for the voting process of the Bitfilm Festival for Digital Film. Since the year 2000, the Bitfilm Festival has been showcasing films that use digital technology in a creative and innovative way. It takes place on the Internet. However, physical screenings of the films will be held in Bangalore and in Hamburg. Each of the 59 nominated digital animations has its own Bitcoin account, and users worldwide may vote by donating Bitcoins to the films they like anonymously and without any transfer costs. The donated money will be divided among the most popular films (the films with the most votes/Bitcoins).
Aaron will presents an animated short about Bitcoin which he has produced with an animation team based in Bangalore. Of course, the animators were paid in Bitcoin.
