“Nature and Algorithm” is a 100-day project. Every day for three months, Liu Chang randomly picked a screenshot of a geographic location or downloaded a landscape picture. She developed an algorithm by looking at the textures in the pictures, and with coding she generated images on the computer that visually imitate the original images. Two images from different worlds - Nature and Computer have similar visual effects. Juxtaposing them, Liu Chang sees the project both as a respect for the beauty of nature and technology, and as a question to the relationship between nature and AI.
