In 1994, I wrote a computer program that would allow me to quickly draw images while watching a video on screen. The saving grace wasn't so much in its ability to capture pen strokes as it was to instantly save my images with just one key allowing me to continue to alter, enhance, change or develop the image without ever stopping to come up with some seven digit filename. Sounds simple, and it was, and it allowed me to produce hundreds of sketches in one sitting...just like taking photos.
