    Yes, I second Concord.org, especially as the put what they develop under free license (the LGPL):

    Not free (except to demo):

    Look for physics simulators; example:

    There is a lot of exploration people can do with Google Maps and Google Earth.

    We've collected lots of links from homeschooling; I should put them up somewhere.

  2. Dust is pretty amazing by drerwk · · Score: 2, Interesting · on Simple, Portable Physics Simulations

    My 10 year old showed this to me : http://dan-ball.jp/en/javagame/dust It is not exactly physically accurate, but it is really pretty cool and fun, and much more accurate than I expected.
    And can I say fast for what I thought one could get from Java.

    If you had checked the behavior on Windows:

    wer.exe" http://dan-ball.jp/en/javagame/dust/

                    at java.lang.Thread.run(Thread.java:619)

    How's that for write-once, run-anywhere? Not even Java can give you the same behavior on different platforms when you invoke different programs or provide different input. The web page doesn't validate and may even be miscoded (though I couldn't figure that out for sure.) The browser must clean up the page before passing data to the applet plugin.

    Do you see now why I stick my neck out for Java, even to the point of downloading the entire frickin' JDK and installing it on a five-year-old Celeron laptop, just so I could reproduce the same behavior under Windows? Don't think I would have done that if I wasn't sure I would get some satisfaction from it :-)

    Yeah. Right.

    I don't know why
    I have an odd fascination
    with this little java game
    There are no puzzles
    there are no goals
    it's not quite a painting program
    but it's not quite a game either
