Noses may turn at the idea of placing private spaces behind transparent glass, but glass continues to be one of the most innovative materials around. Privacy glass laces the once-transparent material with liquid crystals which react to an electrical current. When the current flows, the crystals align and the glass appears normal. With no current passing through, however, the crystals return to their previous state, turning the glass completely opaque – while retaining its translucence.
The White Cave Gallery in Beijing, for example, is a luxury parametric-style retail interior with a topographical form. Amongst its features is a VIP room which, after drawing in customers from the street with a visible display, is able to transform the window into a frosted barrier, creating a private viewing space for VIP customers.
