v8 (realistic layer, appended over frozen v7): Look: realistic (V) switches on physically based shading (linear light, filmic tone map, soft shadows, real gold/silver reflectance, translucent tardigrade with gut, claws and eye spots), a photographic third view (F cycles inside / outside-measured / outside-photo, which shows the Terrell–Penrose effect: the dome stays round, it does not look squashed) and the special-relativity clocks by default. Turn it off for the v7 look and Dave's clocks. Details are in the Realism tab.
v7 (Dave's model): the tetragarde gets company. During the moss stage she lays two clutches of eggs in shed cuticles (as real Hypsibius exemplaris do, MATCH). They hatch later into a colony of 8, held balanced: each companion carries one sign of −+ −+0+− +−, she is the 0 hinge, and the total is always 0. They wander the moss, graze algae, and sometimes tun and revive (Colony tab). Patricia's θ clock enters through the electrum ring as an amethyst pulse, tied to the inside 720° cycle.
v6 (Dave's model): over her full inside run (13.2 billion moves, tin 0 → 1) the tetragarde builds her garden inside the biodome in 11 stages, one per rung. Meanwhile the outside world clock only moves from 0 to 40%. S compares this with special relativity's clocks.
Dave's TARDIS: a tetragarde encased in a gold ring (79%) and a silver ring (21%), which together make one 100% electrum ring. The ring makes a homeostatic biodome moving at 0.6c, "the speed of light and time" (MODEL). F switches between the co-moving view (stars aberrated and Doppler-shifted, the dome round) and the outside frame (the dome contracted ×0.8 along the motion).
You are inside the event horizon with tetragarde. In Dave's model {{1 gravity{{t=0 time}} everything is held at g = 1 and t = 0, so the scene is frozen and only your viewpoint moves. Dave's v2 rule: the bubble holds a budget of 13,200,000,000 moves; each is 1/N, and t only becomes 1 when all are spent (step with the buttons, ., A auto-run, E jump to end). v3: the interior runs on Dave's homeostatic ladder ±[10, 9, 6, 5, 4, 3, 2, 1, 1, 0, 0]. Press Walk the ladder (Space) to step down to the zero point, the mirrored, breathing state −+ −+0+− +− that an outside reading calls 0; G toggles an optional comparison with what general relativity predicts; 0 returns to t = 0.
