This project starts with the question that what is the real form in object. Everything in the world are created, disappeared, and destroyed. This process is ongoing, but most case, we think it is not happen in realtime. But if we can compress the time, for example 100 years to 5 minute, we can see most objectâ€™s form is changing so quickly. In this respect, incomplete form is more similar to real and I try to express this using by artificial smoke.
