Wing identity plays with the "ing" concept contained in the name Wing itself. In English grammar, "ing" usually conveys the idea of "NOW". To follow the concept, the whole identity system plays with "____ing" to allow people fill the blanks and make the information they want to fill up to date. It is flexible. People can fill the blank space by whatever they want to say, write, draw, or any kinds of forms' DIY they want to increase the fun of using the whole identity system.  This way decides each business card, mail, note, etc. they send out is different and "new released" at that moment according to the information they put.
