Attention: This page contains several JavaSketches. If this is the first JavaSketch you've encountered since starting your browser, it may take a few moments to load. (Look for an illustration to appear at the left.) After loading the first JavaSketch, your browser will be able to load subsequent JavaSketches and pages much quicker. Please be patient. Once the illustration appears, you can interact with it by dragging the red points.

Sketches
These pages demonstrate various JavaSketchpad capabilities. Some are recent; some were created to demonstrate earlier versions of JavaSketchpad. (JavaSketchpad is a component of The Geometer's Sketchpad that allows you to export dynamic sketches you've created in Sketchpad as standalone applets on the Internet.)
