Mark Pesce is a father of VRML, \'virtual reality markup language\' and is an expert in new media, including bittorrent and youtube. He speaks at venues as far ranging as New media conferences and the Burningman festival. Some people know him as an, ahem, \'guru\' in new media distribution, others know him as a psychedelic intellectual. I know him as an interesting person with an avante guarde notion of the future and as possessing the ability to articulate said notion, in the context of modern day science.
