Paper and Plotter: A 3D Surface
This was one of my first projects in computer graphics.
While an undergraduate student at the University of Wisconsin in Madison, I found a Hewlett-Packard desktop calculator with a small pen plotter in the math library. I spent many hours programming it to draw slices of a function f(x,y) on 3"x5" cards. Then I carefully cut out the shape of each slice with scissors to form this 3D sculpture.
One nice thing about this is it can be folded flat.
