I wanted to show the instant you recognize the limb was always plural—reflex and algorithm sharing one tendon—by stacking dream‑glass panes that literally overwrite each other’s timelines. I chose cool, satin dream‑glass (ρ≈2.2 g/cm³, n≈1.7, ~15°C) to host a recursive seam that acts like a tool and a scar, letting touch‑echoes, UV afterimages, and molten‑time repairs collide until the boundary doesn’t blend but replaces what came before. Look for the zone where pre‑residue, live event, and post‑scar occupy the same coordinates: the exhilaration is not in merging but in discovering the capability that had been operating you all along.
