Circus
A circus drawn with code and played by your song: the big top at night with its bulbs chasing on the beat and the curtains opening on the drop, the ringmaster in the spotlight, a flying trapeze whose swing keeps the bars and whose catch lands on the downbeat, a juggler throwing real siteswap patterns that change with the song, a wire walker who wobbles on the beat and recovers, and a grand finale with every act at once.

| SensitivityBounded overall audio response | Audio | range | 1 | Yes | No |
| Spectrum rangeHow much of the 40 Hz to 14 kHz range the visual spans, from the bass up. Lower it to give the bass and mids more of the bars | Audio | range | 1 | Yes | No |
| Frequency scaleHow the bars are spread across the frequencies. Log spreads them by octave, mel by how pitch is heard, and linear by hertz, which gives most bars to the highs | Audio | select | log | No | No |
| Auto-levelLifts every part of the spectrum to its own recent range, so quiet highs move as much as loud bass. A note held for several seconds settles lower as it adapts. 0 shows the raw spectrum | Audio | range | 0.8 | Yes | No |
| Primary audio sourcePrimary audio source | Audio | select | bass | No | No |
| Frequency focusWhich part of the spectrum drives this visual; while no explicit audio source is set, the motion envelope follows this selection | Audio | select | full | No | No |

| Ambient bedProminence of the standing background layer behind the beat-born elements | Effects | range | 1 | Yes | No |

| Audio contributionMaximum contribution from the primary audio route | Audio | range | 0.55 | Yes | No |
| Audio dynamicsHow much of the band's movement reaches the visual. 1 = full dynamics; 0 holds it at a steady level for a calmer, more constant look | Audio | range | 1 | Yes | No |

| Symmetry and tilingReshape the whole picture: mirror it, fold it into a kaleidoscope, or tile it (the plane groups p1, p2, p4m and p6m) | Shape and symmetry | select | none | No | No |
| Kaleidoscope foldsHow many mirrored copies go round the kaleidoscope | Shape and symmetry | range | 6 | Yes | No |
| Symmetry angleTurns the mirror line, or the kaleidoscope, in degrees | Shape and symmetry | range | 0 | Yes | Yes |
| Kaleidoscope spinHow fast the kaleidoscope turns, in turns per bar of the song (0.25 is once a phrase) | Shape and symmetry | range | 0 | Yes | Yes |
| Tile sizeEach tile's size as a share of the frame | Shape and symmetry | range | 0.5 | Yes | No |
| Tile gapThe gap between tiles, as a share of a tile; it shows the background colour | Shape and symmetry | range | 0 | Yes | No |
| WarpBend the whole picture: a twist, a bulge, waves or ripples that move once a bar, a polar unroll, or a fisheye lens | Shape and symmetry | select | none | No | No |
