I am now retired and living on the Isle of Man, my background is as varied as it gets, ranging from Information Technology to Graphic Designer and 3D VFX Artist, using and teaching Autodesk Maya, Softimage, and Smoke, one of more enjoyable positions. Since Moving to the Isle of Man I try to keep myself to myself and work on the house, I don't do much with regards to Amateur Radio or Electronics anymore, but I am still interested in the hobby and may well get back into it one day....
