The article discusses how LaserOrigami allows users to quickly create 3D structures that do not require manual assembly. LaserOrigami bends the workpiece by distributing the heat over a larger surface. By moving the workpiece away from the laser, it defocuses the laser. This distributes the laser's heat over a larger region. In addition, LaserOrigami further distributes the laser's heat by repeatedly running the laser back and forth over the region to be bent. LaserOrigami modifies focus by moving the cutting table up and down. LaserOrigami offers two types of interfaces. The first one is a traditional CAD-style interface, which researchers created as a master shape library for Microsoft Visio. The key idea behind LaserOrigami is that it achieves three-dimensionality by bending the workpiece. LaserOrigami accomplishes this by heating selected regions of the workpiece until they turn compliant and bend under the forces of gravity.

There are a wide variety of ways to present information at the front of a classroom. These include chalk on a blackboard, markers on a whiteboard, pens on transparencies, and computer projection systems. While computer-based presentation systems provide many opportunities both in and out of the classroom, there may also be many limitations. In-class spontaneity and dynamic exposition might be restricted. Class preparation time might increase dramatically when compared to the amount required to prepare handwritten materials. Certain presentation techniques may no longer be available. This paper will introduce a computer-based presentation system modeled on handwritten transparencies. It will then discuss how it addresses the above issues as well as how it can be used in and out of the classroom. These will be explored in the context of its use while teaching an undergraduate discrete mathematics course. Copyright 2004 ACM.
