The following applet loads the entire MASON toolkit so it may take a second. Please note:

- 3D demos cannot be run unless your computer has Java3D installed.
- One or two 3D demos cannot be run as an applet period: they use too much memory.
- Mac web browsers create some funkiness. Their Java is not hardware-accelerated and the 2D graphics is very slow. You'll have more luck running MASON directly as a Java 1.3.1 application. See the main web page for more information.
- Mac web browsers except for Safari operate best when the Java 1.4.2 plugin is running.
- Once a simulation is running, you can start another simulation under the File menu.
- If you close a display, it is hidden -- you can get it back under the Displays tab in the console window. If you close the the console window, the simulation is quit.
