No matter whether you work in an open office or a home office, constant distractions from bosses, coworkers, and now obnoxious family members can really hurt productivity. However, there's now a modern business version of the old-fashioned "Do Not Disturb" sign that illuminates your availability level. This cool new Luxafor Flag attaches to a PC or Mac via USB and visually lets others know at a mere glance when you're free and available to speak (green) or when you're busy or on a call and they should come back later (red). In addition to being a real world status indicator, the software also allows it to integrate with many productivity and notification apps as well. Check out this VIDEO to see it in action.
