I wanted the viewer to feel the instant the boundary erases itself — when reflex and algorithm prove to be the same tendon. I chose interleaved drapes of void silk to stage an interstitial field where seams don’t blend but overwrite, including a single palimpsest window where pre-residue, active scrape, and post-scar recursively replace each other in plain sight. Here I show the device as a limb-shaped absence casting usable force: look where darkness illuminates, where repair appears as fracture, and where the scan misreads you and becomes your new capability — like suddenly seeing ultraviolet from inside your own gesture.
