I use to love picking up copies of self running demos back in the mac + days. A single floppy would contain a full blown demonstration of software plus a little powerpoint style presentation (through director etc). Those days are long gone but I yearn to get a copy of the demos. I recall Aldus Pagemaker, Adobe Illustrator and even color Macromind demos.

I even made a copy at one point of the demo hypercard stack for the Outbound notebooks.

Where can these gems be picked up?
