I made this thing during the month of April 1987, before I even knew about computers. I was trying to accomplish the same thing with it that I try to do with my blog.
Every day during that month, I found something small. At night, I'd put the object in a little see-through plastic box. Then I'd glue the box shut. At the end of the month, I poured plaster of Paris into the pink frame, and stuck all 30 boxes in place. I was trying to save a tiny colorful piece of each day.
