Whether it's your first year in the classroom or you're a seasoned veteran using TI technologies, you'll have a tough time choosing from the 400+ sessions. http://education.ti.com/us/t3denver ************************************************************** HYPERGAMI AND JAVAGAMI http://l3d.cs.colorado.edu/~ctg/projects/hypergami/ HyperGami and JavaGami, created by Ann and Mike Eisenberg, are software environments for designing and building paper sculpture. Choose from a number of starting polyhedra, which appear in a 3D window alongside a corresponding "folding net" in a 2D window. Employ both built-in features and the embedded programming language to customize the polyhedron, stretching or shrinking the polyhedron along its axes, truncating it at vertices, or adding pyramidal caps to faces. After the user customizes the new shape, the software attempts to generate a folding net for it, and offers a variety of paint tools to decorate the folding net.
