Microsoft has a new tool to help people communicate through artwork. The technology is called Expressive Pixels, and it lets people communicate through animated visualizations.

Expressive Pixels introduces an authoring app combined with open-source firmware, peripherals, documentation, and APIs that allow users and makers to create animations and then display them on a range of colorful LED display devices.

With implications in areas spanning from accessibility to productivity, creativity, and education, the technology’s potential for growth is limited only by the imaginations of its users and community—and the app can now be downloaded for free from the Microsoft store.
