How does it work? From Mauricio Melo: Ideally there are two devices even though one device can work fine. You set one up at home somewhere where it can be seen by any of your family members and plug it to your home network. Set the other one at your office location and plug it to your office LAN. At any given time during the day, press one of the icons and your home device will reflect your current mood state sharing it with your other significant or a family member. If there is only one home device, it can be accessed through a regular webpage or cell phone.
Web are you is a networked emoticon device to let people back home know if your mood at work/school is happy, sad or upset.
