My husband is always telling me that the computer is nothing but a tool. One day, I spotted some antique tools at a garage sale and came up with the idea to show the progression of tools from then to now. I also wanted to say something about the environment. Back when the tools were simpler, we had a “greener” planet. As we became more industrialized, our planet got “browner”. I do believe we are beginning to think “greener” again.
