Fossils & Archaeology
A fossil's story drawn with code and played by your song, after the world's natural history museums: the mount's blueprint drawn bone by bone on the beat, a dig strung in its grid of squares and brushed down a square a beat, the rock's periods with their ages and fossils, a skeleton mounted in the great hall turning its head to the beat, the prep lab chipping the rock from a skull, and a wall of cases with an amphora put back together from its shards.

| OpacityVisualizer opacity | Transform | range | 1 | Yes | No |
| 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 |
| Burst intensityGlow and trail swell on sharp hits; 0 keeps bursts off | Audio | range | 0 | Yes | No |
| Ambient bedProminence of the standing background layer behind the beat-born elements | Effects | range | 1 | Yes | No |
| Wake lengthHow far motion trails stretch behind beat-born travelers; 0 removes the wake | 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 |
| Audio attackEnvelope attack in milliseconds | Audio | range | 45 | Yes | No |
| Audio releaseEnvelope release in milliseconds | Audio | range | 240 | Yes | No |
| Geometry scaleGeometry scale | Geometry | range | 1 | Yes | Yes |
| Motion directionRotate the animated visual pass to face this direction; the general background stays fixed | Motion | select | none | No | No |
| SpeedTime-based motion; default major cycle is 6–12 seconds | Motion | range | 0.1 | Yes | Yes |

| Beat responseHow hard every engine hits on each detected beat | Audio | range | 1.2 | Yes | Yes |
| Beat smoothingHow long each beat hit rings out before it settles | Audio | range | 0.35 | Yes | Yes |
| Beat attackSeconds for a hit to swell to full. 0 snaps instantly | Audio | range | 0 | Yes | Yes |

| 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 |
| Warp amountHow strong the warp is | Shape and symmetry | range | 0.5 | Yes | Yes |
| Warp centreWhere the warp is centred in the frame | Shape and symmetry | select | centre | No | No |
| SpecimenWhich skeleton: a theropod (after Tyrannosaurus), a long-necked sauropod (after Diplodocus), a ceratopsian with its frill and horns (after Triceratops), or Rotate for a new one each section of the song | Fossil | select | rotate | No | No |
| DiscoveryHow much is found on each beat: the bones drawn, the squares dug, the rock chipped away. At 1 the skeleton is whole by the phrase's sixth bar | Fossil | range | 1 | Yes | Yes |
| DrawingThe blueprint's paper: white line on Prussian blue, a field notebook's sepia on cream, or the line glowing on the dark | Blueprint | select | cyanotype | No | No |
| LabelsHow many labels: the bones' names, the dimensions and the scale bar, the periods and their ages, the case labels and catalogue numbers. 0 shows none | Museum | range | 0.7 | Yes | Yes |
| GridHow strong the drafting grid, the dig's strings and the stone's bedding are | Museum | range | 0.6 | Yes | Yes |
| Gallery lightHow bright the lamps, the skylights and the case lights are. Museum light: slow and low, rising with the song, never a flash | Museum | range | 1 | Yes | Yes |
| DustDust in the light, pencil dust on the sheet and the chips of rock flying in the lab | Museum | range | 0.5 | Yes | Yes |
| VariationAnother dig of the same story: the specimen chosen, the order the squares are dug and the rock chipped, the catalogue numbers. The same number always gives the same | Museum | range | 0 | Yes | No |
