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 (balldrop.zip) but not the compression utility. My third try didn't even get me that far.
Way to complicated to use. In the end I just gave up.
