Years ago I discovered that the Renaissance used glass in their mediums of oil. This reflected the light in the room and came out of the viewer. Much like stain glass windows it is a different quality light that is ambient. To illustrate the power of this kind of light one only has to look at the plight of newspapers. The reading of them is 2 dimensional and quiet. Compare that light to the computer where the light is coming out at the viewer from behind the image. The same thing happened to the movie industry when television was 1st available.
I have always been interested in what happens to form when combined with the elements of time. I believe that everything in the universe is affected by time and time is always in a state of transition.
