Just some conceptual designs for a project.
If you go about making this, I think a shiny colour for the yellow will make it pop more. ^^ Like a sort of "car paint" finish to make the sound wave more electrifying. It may look cool, it's just my small opinion. ^^ The idea of the light hitting it in certain places and making it shine, for someone standing still, and looking over at the board as it passes, it may give the effect of movement.
