What stays fixed when the table changes shape?
Select an element, then compare Oblique and Develop. Follow the same element and its structural address.

About this tool
What you are looking at
The proposed model places all 118 known elements on a non-closing, widening helix, with hydrogen at the lower pole and helium at the upper pole. Element order and the n+ℓ and 32-column addresses stay fixed. Radius, spacing, and camera orientation are choices made for the display. The pentagonal shell-closure guide and optional C60 face study are comparison layers: they do not replace the helix, relabel cage vertices, or establish a realized application.
How to use it
Choose the Helical model or Pentagonal closure, then select an oblique, side, axial, or developed view. Drag to turn; pinch, scroll, or use plus and minus to zoom. Select a tile or use Inspect an element. With the canvas focused, arrow keys move through elements and R restores the selected view. Develop performs a Janet cut-and-unroll rather than a camera projection.
The helix widens without closing, as described in the paper, with H at the floor and He at the ceiling. Element order and n+ℓ / 32-column addresses stay fixed. Radius, spacing, and camera orientation are display choices. Shell-closure markers run from Ne through Og. Develop performs a Janet cut-and-unroll; it is not a camera projection. Structural addresses remain fixed. The comparison guides and face study leave the authored helix unchanged. Drag to turn the model; pinch or scroll to zoom. With the model focused, use the arrow keys to move between elements, +/− to zoom, and R to restore the selected view.
