Searching for HyperCard stacks

As mentioned earlier, I bought an iBook G3 so I could play around with Mac OS 9 some more - one of my favourite operating systems. This time around, I'm also taking a look at HyperCard, something I never experienced but am quite interested in. Since I know many of you grew up with Apple machines and possibly HyperCard, I was wondering if any of you have any recommendations for fun, interesting, or otherwise fascinating HyperCard stacks.I can see the potential all over HyperCard from the mere demos alone - and now I want to see what smart people could do with it.
