Slideshow
Demo format consisting of a sequence of static images or graphics with music and transition effects, used when real-time rendering is impractical.
A slideshow lets demo makers focus on visual composition and animated effects without implementing full real-time 3D rendering. On the Commodore 64 and Amiga, slideshows were a popular vehicle for digital art paired with SID or tracker music. Simple versions display a single large bitmap; more sophisticated ones layer palette animation, scrolling effects, and carefully timed transitions to create motion within a static image. Many classic chiptune compositions were originally conceived as underscore for slideshows, teaching composers how to structure pieces for visual storytelling.
