In addition to minor interface tweaks, I have spent the past few days working with the nub views (driving, head tilting, and emotion). The emotion nub replaces the buttons and allows for smooth transitions between colors. Additionally, the movement of the head and tilt nubs is now smoother because of animations back to the start position. Optimizing images, such as the silhouette image used to access the child view, was necessary for retina displays. Finally, I modified the phrases buttons for grammar and also to accommodate more than one line of text.
