This particular use-case can be interesting for companies designing advertisement boards and installations. You can see citylight boards and custom advertisements all over shopping malls and supermarkets, sometimes even on the streets. These boards are more spectacular and economical if they have remote controlled dynamic content instead of a static picture. With the Ratherboard, you can use a public Wi-Fi network if available or GPRS to control your citylight.
Imagine a “Facebook-connected” advertisement board which displays let’s say 5 adverts. Users can connect to the control unit (a Ratherboard) with their smartphone to change between adverts, like and share them. These likes and shares would show up live on the advertisement board and in the user’s own Facebook feed. With the Ratherboard this is amazingly simple and innovative.
