Another Attempt. This one is useful.

I think the last post was too short and did not explain enough.  I am attempting (as are many others) to put Wolfram's CDF documents online.  It seems like it is possible to view in major browsers (unless viewing on a Linux machine).  If you are using Mac or Windows and you do not see anything for this post and the last, just click on the icon in the middle and download the plugin.  This is like the Adobe Flash plugin or any other kind of plugin.  You need it to view the content.

If this works (and I work out all of the bugs, like re-sizing of the last entry), I hope to put a lot more on here.  It is just easier than making movies and trying to explain everything.
