The author spent 6 years building a 1000-pixel display made of wooden cubes, controlled by a web interface that allows anyone to interact with it. The project involved designing and building a custom CNC machine, creating a web app, and developing a mechanism to turn the pixels. The display can be used in various modes, including user-submitted images, real-time collaboration, and idle modes. The author plans to share the display with the public and potentially install it in a coffee shop.
