In today's image, we see a video where the tones the sound are used to represent different colors in the image. The red colors are represented by the lower tones while the blue is represented by the lower tones and the green, the middle tones. This is a way of representing the image in a different way so it can be "seen" even by one who can not see the image directly.

My podcasts are available in video form through this YouTube Channel.
