I use this applet to help students visualize a sampling distribution. It's a good visual, but doesn't allow for any student interaction or discovery.

This looked like an interesting site. Unfortunately, it was impossible to get
it to work. I tried to access the ball drop on several different occassions
(just in case it was my computer acting up) but I was never successful. On my
first try I ended up in a commercial site for software downloads which I could
not get out of. On the second try I was able to download the first part
( but not the compression utility. My third try didn't even get me
that far.

Technical Remarks:

Way to complicated to use. In the end I just gave up.
