I found IntelligentPad on an old Macintosh magazine cover CD, was intrigued enough to run it, do some digging, do a screen recording and put it all in this blog post. I'd never heard of it before but you can easily see the things it has in common with Interface Builder (which was new at the time), Hypercard (ditto) and even things that followed it like Fujitsu's TownsGEAR, Microsoft's Visual Basic, Borland's Delphi and Apple Research Lab's Squeak.
