Palette cycling, sky, sun and moon, clouds, starfield, rain, snow, petals, leaves, fireflies, waterfall, ocean, campfire, lava, aurora, lightning, mountains and a season scene; scanlines, vignette, screen shake, flash, dither fades, iris wipes, dissolves, mosaics, glitches, sparkles, explosions and confetti. Home opens on a live scene in the palette's season and a strip of all eight palettes. pixel adds Canvas.Cycled, Sprite.At, SpriteOf, Kit.Toward and Kit.Shot, which spends a cue under Reduce Motion so it never replays; display exports Reduce. Gallery grids and the sidebar are one Tab stop each.
