So this is something I just discovered today and I would love to learn more about.  The artist takes the tape out of a cassette and uses it to form the person's outline and hair.  I love alternative mediums, and Erika Iris is one who uses a lot of them to create art.  Take a look at her website  http://iri5.com/tape-art/  to see more cassette tape art as well as some other amazing pieces made from different materials.  
A collection of inspiration...
