I can't believe one little bouncing ball demo became the entire marketing directive for the whole product line. How sad! This is the sort of marketing that let C= sink in the first place and we are carrying on the tradition!
On the contrary, Commodore wanted nothing to do with the Boing Ball. The Checkmark and the color swatches were their marketing icons. It was the post-Escom Amiga Technologies / Amiga International that used the Boing Ball, a pattern that has persisted through to today.
