A clamshell box is a particular form, traditionally used in libraries to protect, preserve, and store manuscripts of the past. I first made them to protect the books that I had constructed. Eventually I began to think about the clamshell box as a metaphor. I built them to contain my inner thoughts, memories, feelings, and ideas. Unlike the traditional form, however, I opened a side to frame an interior view. Mind the Gap is a clamshell box that stands with two sides to be viewed.
