He has created a whole series of videos for the Raspberry Pi and a visit to his channel should be a first port of call for Raspberry Pi Newbies. http://www.youtube.com/user/RaspberryPiTutorials/
He is also a regular writer for Linux User and if you are getting into the Pi and Linux a subscription wouldn't half be a bad idea! http://www.linuxuser.co.uk/ (Shameless Plug)
It also just shows what our young people can achieve when they put their minds to it!
