Use pixels to represent pictures and shapes.

How it Works

Create patterns and shapes using a board of colour-flipping tiles - a simple 'digital' display.

Things to Try or Ask Around the Exhibit

  • What shapes and pictures can you make?
  • How complex an image can you make with this board?
  • What if you had a larger one?


These squares are examples of pixels, which are used to create images on digital displays.
