I wanted to make visible the moment you realize the device was never external—reflex and algorithm are the same muscle already in motion. I chose diagonal slabs of liquid stone in unstable fall, cross-written by scan-fault pre-echo and an erasing magnetic dust surge, so the “seam” doesn’t blend but overwrites; in one palimpsest band, pre-residue, live event, and after-scar recursively replace each other until time loses sequence. Here I show boundary as capability: the image should feel like suddenly seeing in ultraviolet as the field itself learns a new reflex and takes you with it.
