Maslow's Hierarchy of Needs

I am working on a new project that will see bird nests encased in glass etched with the words that describe each layer of Maslow's Hierarchy of needs. The nests will get progressively larger and be stacked in a pyramid shape.  I bought a dremel today and will be etching the glass with it. I cal see the dremel becoming part of many of my projects.
