Ephemeral and luminous geology of a movement in space

Stratum is an interactive installation with which the user can influence a “territory of light” by the gesture. The path of the hand above a capture interface is materialized in space by means of light strata. This reaction triggers a visual reminiscence of the gesture, which becomes visible and tangible, like an ephemeral geology of movement.
