Storyboard:  

In this process, we envision our project as a card-based music player which contains functions below

Choose Playlist:

By putting the card on the player, the Spotify API should reach to one's smart device and play the playlist accordingly.

Record or Edit the Playlist:

By clicking some button, users should be able to create their own playlist into a physical card. And the user could decorate the card.

Share:

Users can customize the card and give the card to friends who also have the player.
