Relaxing Sights and Sounds
Select a theme, and then access any of the puzzles under it with no moving cores. After 1 minute, the music will change. After 5 minutes, all images on the screen other than the background animation will disappear. After 10 minutes, the music will change again to a generally more relaxing theme (which is probably what the game's description in the DSiWare shop is referring to). Note that not all themes follow this pattern, and the music for a few themes will change again after 20 minutes of inactivity.
