I particularly enjoyed this class assignment because of the opportunity to combine visuals with sound.  My goal was to create board where the user could place notes and then have them be played in unique ways.  This is what led to to being able to spawn the lines from any side of the screen to play the notes that were placed.  Notes placed at the top of the screen have a higher pitch than those at the bottom (except for the drumsticks).  This combined with lines coming from all sides allow the musician to experiment with a variety of tools to create interesting songs
