I wanted to show the moment the limb realizes the screen was its own tendon all along. I built a vertical core-sample of soft diamond—each stratum a reflex epoch—where ECG-crystal, delaminated glass, and scan-fault fossils overwrite one another; a laser-cut seam performs pre-residue, active event, and post-scar in the same wound so the boundary doesn’t blend, it replaces. I chose bioluminescent cold light that yields like skin yet cuts like prism so the viewer feels the ecstatic vertigo of discovering a capability already inside their reflection, acting back.
