HyperCard was a program for the Macintosh computers that I used in the 1990s. I was not a huge fan of the application, but I created my stacks and did what I could with it. My use of HyperCard was for storytelling, if I recall correctly.
Matthew Lasar has a more in-depth review of what HyperCard was and how it was used graphically. I never used it for graphic tasks, although I did do a fair amount of work with MacDraw back in the day.
So, if this were 1995 and if I was using my Macintosh Classic II or if this was 1998 and I was using my Mac Color (mine were a bit behind the times), then I would have HyperCard open and I would be making character notes and using the application to create stacks. One stack for the chapters, as an outline, and one stack for the characters. If I were using this system for the Easter Wolf story, I'd have all of that stuff prepared and set aside.
By the time 1999 rolled around, I left my Macs and went with PCs. It was not until 2009 that we acquired a new Mac Powerbook and returned, as it were, to the fold.
