Jemina's Refraction - Angela's entry

I looked up different types of refraction & liked the mysterious quality of using sound waves to "see" what we otherwise cannot. As usual, this took me on several enjoyable tangents:

"Seeing" with the tongue  http://discovermagazine.com/2003/jun/feattongue#.UkVew2TTV0o  

Buoys which collect sonar to describe rock/earth density. http://youtu.be/9Kp1fKy9kOo 

Sonar as harmful to dolphins, whales and other marine life.  http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0060953 

For Jemina's Refraction book (top), I used a relaxing, paint-by-number  sort of approach. When finished, I wanted to continue and so I did another version for myself (bottom). Happily, it may also help me toward a solution for my first MA Fine Art challenge. Thanks esketchers!
