Something a bit further then just decoration, a Smart with Oled panels that allow the user to choose the colour during the day, also permit to have a light glow during the night, so it becomes visible in dark roads (it´s a small car). In the doors with can also write messages, to comunicate with others! The ceiling is covered with photovoltaic cells, for the batteries and panel system. It´s an interactive Smart, for those boring days stuck in traffic, hehe.
