I work at cool company called DIPS. Not long ago developers were challenged to spend 24 hours brainstorming and prototyping our own ideas. For winning most votes with an app I received a Lego Mindstorms kit as a traveling cup. The set came with a new challenge: build something cool. The result is a monitor that notifies me and my team when we check in good or bad code. Technically it uses TFS API and monoBrick to start corresponding motion sequences. The blue NFC tag takes you to details page of the build.
Btw, we are looking for co-workers, check out dips.no
