The past Wednesday I've had the honor of meeting Mr. Nolan Bushnell in person at Campus Party Brasil 2013 (http://www.campus-party.com.br/
). It was a memorable evening, he gave me his autograph and I gave him the two books I wrote on the early history of video games in Brazil ("1983: The Year of Video Games in Brazil" and "1984: The Video Games Fever Continues"). He said, jokingly, that he was going to read the books in spite of the language barrier for they're in Portuguese.
Mr. Bushnell was extremely nice to me, meeting him was a dream come true. His talk was great, you may check the pictures here:
