The official account names harmonic sine waves, while the supplied inspection associates hash choices with palette and ridge frequency. Changes in contour and repetition alter the apparent rate and character of recession. The documented drag interaction changes the encounter with the tunnel. The still comparisons below establish form and colour, not the exact motion of a full interactive session. [^S01][^S02][^S03]\n\nThe comparison below uses static previews.

The repeated points make the recession pulse between star and circle. Narrow dark intervals give each coloured layer an edge. [^S09]\n\nIn #1, green and yellow outer bands lead through violet and warm orange toward a dark centre. Numerous fine teeth intensify the surface. The eye has to negotiate both radial depth and rapid local alternation. [^S09]\n\nIn #10, black-and-white curved wedges alternate with coloured ones around a common centre. The striped surfaces twist visually against one another, making inward movement less stable than the regular rings of #1. [^S09]\n\nIn #20, nested square contours turn the tunnel into an angular shaft. A rainbow sequence spans orange, green, blue and violet as the squares recede. The change of boundary geometry alters the spatial reading as much as the palette. [^S09]\n\nThe supplied AB5D holding record identifies edition 711 as the collection example used above.
