Concepts/Inspiration for Installation Project

I know that I want to use popcorn as my main material. It is something that is cheap and can be manipulated in multiple ways. I am thinking of putting my installation outside. Because I live off-campus I will be taking advantage of the fact that I have access to more scenic locations. Since my material is popcorn I am thinking of installing my work in a cornfield as I the idea of putting the manufactured material in its place of origin has strong conceptual potential.
