The most amazing and inspiring motions and forms can always be found in nature. By combining different materials and placing them under different circumstances, we can achieve natural patterns and forms that are not only beautiful but also orderly. This work was inspired by the ferrofluid and the reaction of this liquid to magnet. The liquid used in this work is a combination of micronized iron oxide particles, oil, and citric acid, which is similar to ferrofluid. This liquid also reacts to magnet, and depending on its distance to the magnet and its strength, it makes different forms that follow the same rule. In `Black Wave,` which is an interactive work, humans are also added to this reaction as a third factor; they can control the reaction and feel themselves as a part of it.
