Ah, we always loves these cool little projects for Windows Phone enthusiasts.
Take this case where, as our title says, 28 separate Windows Phones were linked together and controlled by one phone using Bing Maps. As a result, when you scroll at the one Windows Phone, you'll move the map on those 28 screens at the same time. What's it called? How about "Bi(n)g Maps", eh?
Useful? Not really. Ingenious and clever? Definitely. (See the similar 144-screens linked together for a world-record here)
