Unfortunately I know very little about Korean artist Minjeong An (her website is currently down), but these are just a few of her incredibly complex self-portraits illustrated using some kind of information visualization. My guess is she’s using a mix of actual data, or a perceived translation of sensory input along with simply beautiful drawings. You can see a bit more on Prosthetic Knowledge and 50 Watts.
Relationship between sound and color. If you could actually "hear" the extremely high frequencies the red, yellow and blue (primary color) light waves are vibrating at... you would hear a Major chord. If you could "see" the sound of notes in a major chord relative to the same "rainbow scale" used by light, you would see notes and chords in primary color
