Dividing a room with light. Venezuelan designer Pablo Pardo's smart, mulltipurpose Ventana gives light a new meaning. Ventana, to be released in September, is a space divider, window shade and a light source. The screen has light bulbs on its lower rod and can be pulled down like a window shade. The light bulbs brighten the semitransaprent double vinyl or can be rotated to change the direction of the light.
