Home Appliances Design Serena Anti-gravity Humidifier by Mingxi Li Inspired by optical illusions and the art of natural gravity, the visual effect of water droplets flowing backwards breaks the conventional perception. Based on the principle of visual persistence, LED lights and precise control are used to achieve the illusion of anti-gravity, combining humidification with artistic beauty. The challenge was to synchronize the flow of water and the lighting effects to ensure the perfect combination of function and vision. At the same time, the shell needs to have high light transmittance to meet the aesthetic needs of modern homes.
