Thanks for this easy to use development platform. I used spark core for a tiny proof-of-concept prototype for recording my (psycho) galvanic skin response. Its mobile and (of course) hooked up to the internet, so that data can easily be fetched by a database. The Prototyp was shown at Creative Lab HAPPY HEALTH at DMY-Design Festival Berlin.
Here is a two minutes demonstration video https://www.facebook.com/photo.php?v=10152874331743574
