Andrew Griffiths
Andrew loves to create things, and if its graphics related all the better!  It started in Durban, South Africa at the age of eight when an excentric headmaster started teaching his students BASIC programming on the C64.  From this moment he spent much of his time with computers trying to make them do ‘neat’ magical un-computerlike things.  In 1993 he fell off his chair when he saw a demoscene demo for the first time.  This sparked a career goal change from actor to programmer.  Since then he’s been heavily involved in the demo scene, attending and create demos, graphics, music, photos and videos as many demo competitions as he can make time for.  For the last 6 years Andrew has been programming in the games industry in the UK.  He now works as a lead programmer at Deep Red Games and has fond memories of his days at Awesome Developments.
