The is a 4x6 window for a light. Bottom layer uses a transparent red or blue color, then use or manually swap filament to black for about the top 4 layers. I leave to you to make you own box. strip lights all all that are needed. They can shine from the side if for more indirect lighting. Alternately you could step lights in sequence using Arduino. Chips can only source or sink a maximum amount of current so you name need a transistor or FET.
