Sorry, had not read the whole article -- had clicked in from another article linking to "The bouncing ball", and mistook "Specific platforms" as a subsection of that. Changed my new links to be citations for the "bouncing ball theme has reappeared" claim.
Historically, the bouncing ball has been a popular theme in computer [[demo effect]]s since the 1950s, when a bouncing ball demo was released for [[Whirlwind (computer)I|Whirlwind]] computers. It later became the primary theme for the early Atari games ''[[Pong]]'' and ''[[Breakout (video game)|Breakout]]''. [[Commodore International|Commodore]] released a bouncing ball demo at the 1978 [[Consumer Electronics Show]], to illustrate the capabilities of the VIC chip. A similar theme was used by Amiga Corporation to demonstrate the capabilities of the Amiga computer at the 1984 Winter Consumer Electronics Show in January 1984. It was a real-time [[animation]] showing a red-and-white spinning ball bouncing and casting a shadow, this bouncing ball became the official logo of the [[Amiga]] company. Within the context of this tradition of bouncing ball demos at the Consumer Electronics Show, CBS Electronics also showed a Bouncing Ball demo for the [[Atari]] VCS/2600, with a spinning and bouncing ball, at the same event. Following these semi-official demonstrations, the bouncing ball theme has reappeared in various demoscene productions.<ref>{{cite|url=http://macintoshgarden.org/apps/vanlandingham|title=Vanlandingham - Macintosh Garden|date=1986|accessdate=2016-03-18}}</ref><ref>{{cite|url=http://www.jimbrooks.org/programming/opengl/boing/|title=OpenGL Amiga Boing|date=2009-03-07|accessdate=2016-03-18}}</ref>
