I would like it so that there is a visual indication of how long the toothbrush timer has been on for, on the face of the Yoto player itself. My suggestion would be to have a single line of pixels around the sun’s face, which slowly either wink out or change colour (from yellow to orange, for instance), meaning that the child using the Yoto will be able to see exactly when quarter, half, and three quarters done for the different quadrants of the mouth.
