I learnt HyperCard when I was young, I found it on my dad's LC when I was bored and started looking at stacks and stuff.
I made an Address Book, which I actually used , a customizable quiz game, various databases, and probably more I can't remember.
The last things I did were a CGI for remote administration on my server (when it was a Performa running MacHTTP), and a program for converting images to text (not ascii art, but each pixel was a zero in the right colour, and 1pt size) mainly for pasting in carracho servers (anyone remember carracho?). And also a Hypercard-chat, with AppleEvents.

I've tried MetaCard, SuperCard, and Revolution, but I still think there's no decent modern alternative.
