Airborne particles are the medium for SARS-CoV-2 to invade the human body. Light also reflects through suspended particles in the air, allowing people to see a colorful world. Impressionism is the most prominent art school that explores the spectrum of color created through color reflection of light. We find similarities of color structure and color stacking in the Impressionist paintings and the illustrations of the novel coronavirus by artists around the world. With computerized data analysis through the main tones, the way of color layout, and the way of color stacking in the paintings of the Impressionists, we train computers to draw the novel coronavirus in an Impressionist style using a Generative Adversarial Network to create our artwork "Medium. Permeation". This artwork is composed of 196 randomly generated viral pictures arranged in a 14 by 14 matrix to form a large-scale painting. In addition, we have developed an extended work: Gradual Change, which is presented as video art. We use Graph Neural Network to present 196 paintings of the new coronavirus to the audience one by one in a gradual manner. In front of LED TV screen, audience will find 196 virus paintings whose colors will change continuously. This large video painting symbolizes that worldwide 196 countries have been invaded by the epidemic, and every nation continuously pops up mutant viruses. The speed of vaccine development cannot keep up with the speed of virus mutation. This is also the first generative art in the world based on the common features and a metaphorical symbiosis between Impressionist art and the novel coronavirus. This work warns us of the unprecedented challenges posed by the SARS-CoV-2, implying that the world should not ignore the invisible enemy who uses air as a medium.

翻译：空气中的悬浮颗粒是新冠病毒入侵人体的媒介。光线同样通过空气中的悬浮粒子反射，使人们得以看见五彩斑斓的世界。印象派是探索色彩光谱最杰出的艺术流派，它通过光的色彩反射创造色彩。我们发现艺术家们描绘新冠病毒的图像与印象派画作在色彩结构及色彩堆叠方式上存在相似性。通过计算机数据分析印象派画作的主色调、色彩布局方式及色彩堆叠手法，我们训练计算机利用生成对抗网络以印象派风格绘制新冠病毒，创作出艺术作品《介质·渗透》。该作品由196幅随机生成的病毒图像组成，以14×14矩阵排列形成大型绘画。此外，我们延伸创作了动态渐变视频艺术作品，采用图神经网络逐帧渐变地呈现196幅新冠病毒画作。在LED电视屏幕前，观众将观察到196幅病毒画作的色彩持续变化。这个大型视频绘画象征着全球196个国家遭受疫情侵袭，每个国家持续涌现变异病毒，而疫苗研发速度始终难以追及病毒变异速度。这是全球首件基于印象派艺术与新冠病毒共同特征及隐喻共生关系的生成艺术创作。该作品警示我们新冠病毒带来的空前挑战，暗示人类不应忽视以空气为媒介的无形敌人。
