CircularBells, a musical toy covertly inspired by science

I published a musical toy (https://itunes.apple.com/us/app/circular-bells/id1062362784?mt=8) that is going to be used for some scientific studies soon.

I have a quick write-up about how I made it here (https://medium.com/@morpheu5/how-i-made-an-artsy-app-based-in-science-a3690164a9ce#.mwt0sz75k) and how I failed at releasing it here (https://medium.com/@morpheu5/how-i-messed-up-my-artsy-apps-launch-e684111de532#.gdgyn1k3k).
