JavaSketchpad DR2 Gallery

These pages contain a number of JavaSketches demonstrating various new (DR2) capabilities. The middle column estimates the complexity of the construction: if Java is exceptionally slow on your computer, you may want to stay away from the "Intermediate" and "Complex" sketches.

If you'd like to add your own sketches to the gallery, drop me a line.
