Project For Earth Art

For my project I am considering using driftwood and seashells. I will use these in one of two ways: 1. To create a celestial constellation (similar to what Nancy Holt did) or 2. I might put some in the water and some on land to represent the degradation of Earth Art or to represent how Smithson's Spiral Jetty was submerged for four to five years and everyone thought that it was gone forever, but it resurfaced.
