This particular piece was made, actually, as a prototype for a class I was teaching to advanced students at the high school level, trying to help them "expand their horizons" artistically. I'm not sure all of them "got it" or even appreciated the experimental nature of making art... many were not willing to risk getting outside the comfort zones of what they'd "mastered"...which is, of course, part of the adventure! There are a variety of materials involved in this smallish painting - cardboard, paper napkins with texture, gesso, cotton string, tape, and many layers of acrylic, even a little oil paint to create a patina.
The idea for this originated from a topo (topographic) map... which, for many of my students, is something completely unknown. Amazing how ideas for art can come out of almost anything - no matter how remotely removed from "artistic subject matter"! (The odd line barely visible a little right of center, is my efforts to scan this image in several parts and piece it together as the larger painting actually is.)
