Every visualizer style with a picture of each, which ones are free, and how to choose the set that plays.
Choosing which visuals play
Open Settings › Visualizations.
Under Scenes, move down the list, which is grouped by style. Highlighting a scene previews it beside the list; pressing Select includes it in the automatic cycle, or takes it out again. The scenes you include are the ones the visualizer cycles through in the music room, and the ones its swipes and Skip buttons step through.
Turn All Scenes On or Off at the top saves selecting one at a time.
Settings › Visualizations.
There are 35 visuals in all. Eleven are free all year, and the Pumpkin Patch is free during October. The rest come with Theatrium Pro and show a small PRO mark. Three of the 35 are Halloween visuals, which appear in this list only while Halloween Mode is on (Settings › Appearance › Halloween Mode); the rest are always listed.

Two engines
Settings › Visualizations › Visualizer Engine offers Live (the visuals are drawn live on the Apple TV, the normal choice) and Video Loops (Pro: ready-made video clips, downloaded once, for an older Apple TV that struggles to draw them live). Once downloaded, a Remove downloaded loops button under More visualizer settings frees the space again. The same More visualizer settings row holds the Info Panel and the Tempo and Colors choices; see How the visualizer keeps time.
