Do you use text emojis in your communication in daily life? I’m sure you will answer “Yes”. It is easier, faster and shorter than writing a message. My concept was to use smiley face emojis to represent emotions and opinions. I hope music from the piano will spread messages like emojis do to people around the world. The smiley face pattern on the piano glows in the dark. We will see them and smile all day with different views between day and night.
