Room IV / Projection
Shadow Sculpture
Exact local time
The central object does not resemble numbers. Drag the light, or use the arrow controls, to disturb its shadow. Return it to the calculated position to recover the time.
Construction
The magenta vector joins the movable lamp to the sculpture. Every piece contributes to the calculated shadow, while the object remains abstract from the gallery view.
How to read it
The shadow on the gallery floor gives the time. A sharp shadow means the light is near its calculated position.
Try the light
Move it away to break the reading, then use Reset light to recover the exact projection.
