←Did this window pop up? If so, allow scripts from this site for the animations to work correctly.

If the LiveGraphics3D boxes on the animations just say "loading" with a stellated star picture, but never actually load, you'll have to increase the amount of memory available to Java.
Note: these instructions show the boxes for my version of Windows2000, but it seems pretty similar for other operating systems. You'll need to find your Java control panel, and then find a blank box that says something like "Runtime Parameters." Click on the box, and type this in (including the '-'):

If you have 1GB or more of RAM, then type -mx512m (all animations will work)
If you have 512MB of RAM, then type -mx256m (all animations will probably work)
If you have 256MB of RAM, then type -mx128m (some of the animations will definitely not work, sorry)

Here are some screen shots of how I did it on my computer: Windows users: Click Start, go to Control Panel, and open the Java control panel.

Now click on the Java tab, and View the Java Applet Runtime Settings. When a new, small window opens up, click on the box on the right (Java Runtime Parameters), and enter -mx512m to increase the maximum memory for Java. Here, the 512m means 512MB. You probably shouldn't go much over half of your memory, so if you have a computer with 256MB, you won't be able to see the 3D Planetary Motion animation (I'll work on this). If you have 512MB in your computer, then type -mx256m in the box. The planetary motion animation currently needs about 250MB.
