Another item I found curious while spending time in Lausanne the the other day: a see-through toilet. Based on a steel-and-glass architecture, the toilet is based on a transparent system: when pressing the “voir” button (which means “see”), the glass gets transparent and it turns opaque when someone is inside and presses the button again. A motion sensor also turn the glass transparent if there’s no motion during a certain amount of time (to prevent people from staying there for too long or in case of a problem) OR if there is TOO MUCH ACTIVITY (no party is allowed in there).
