The symbols for L-phase nodes are horizontally oriented disks, but they're wobbling disks, and so they extend more or less into the vertical dimension, marking out levels in a developmental progression. The D-node is closest to the flattened black disk representing ideally-opaque materiality; its wobble doesn't extend far into verticality. It thereby also represents the first of six stages in a developmental progression.
