Pulse is a great example demonstrating the use of .NET Gadgeteer for prototyping:

“Pulse seeks to visualise information in the simplest and most elegant way possible. By using mathematical processing, a wireless internet
connection and six servo motors, Pulse converts online informations into a tangible graph which is displayed right on your living room
wall. By tilting Pulse users are able to switch between three different information feeds of their choice, all of which are easily programmed
by pairing the device with its online platform. With an overload of electronic gadgets and social media platforms, the online generation is being bombarded by information that is irrelevant to their daily needs. Facebook and twitter feeds consume our focus, when in reality, the majority of the data we are being fed does not
affect us. Pulse filters out the blur, leaving the user with a clear, pure visual representation of the information they seek. “
