Any light source can serve as your creative implement and we shopped for every keychain flashlight, gimick pen and light wand we could find.
But we finally sat down and asked what manner of flashlight would accomadate Lori's most natural and comfortable hand posistion while drawing in mid-air. The answer was to hold the light just like a pencil with instant on/off control directly under the index finger.
Since we wanted to complete each full drawing in one exposure, she needed to be able to switch between different colored pens quickly. We also found that when drawing a large picture we needed the light to be completely exposed on all sides to minimize fading around the edges.
With these parameters, I went hunting for parts at the local electronics and hardware stores and came up with what turned out to be a simple and versatile tool that resulted in some incredible art.
