I take my inspiration from Light and Nature - color, light and motion are my muse- that and a lot of reflection.
I've experienced many artistic media and work with interest in the media themselves...even RGB pixels which are supposed to be just representational are given life by the fact that they live on a color monitor, and are "consumed" by someone else. It is this relationship which I explore: tangible media consumed for an unknown variety of reasons by the subject.
To me, the medium is less important than the choices made about it. I particularly love when the medium itself is brought to a point that transcends it, such as when photography ceases to be a visual rendering and becomes art. There are many more examples- that one is convenient.
My favorite artistic applications are Reflective Photography, 3D Animation, Sharpie Maker on Bond Paper, "Hand" painted illustrations via mouse, Multi-layer Oil Pastel/Chalk, Paint on Leather, Electromagnetic Chromatography, Kaleidoscopic Art, Plastics, Portraiture, Landscapes, Abstract Art, Expressionistic Art, Performance Art
If you really consider what I've said about art, I think the defining factor for me is that I consider that the viewer (or the experiencer...) is the subject of any work... I find Art to be a communication medium, and without some kind of relationship between the observer and the observed I believe there ceases to be communication at all, although I understand "pure art" (art for it's own sake) is different, I still believe it applies, for posterity if nothing else...
In my work, whether it is design, photography, commercial, or web interfaces, I seek to honor this relationship between the person who consumes the media, and the media itself- even if I bend, twist, or otherwise warp their perspective, I am fully aware that the relationship prevails :)
