Customizing a matrix with a Raspberry Pi can be tricky, but Neythen Treloar's project changes that by making it possible to paint an image onto a matrix in real-time from any browser. This isn't the first time we've shared Neythen's work, we previously showcased his matrix-based video game project.
The new project is dubbed Pixel Paint and it's completely open-source for the community to use—the best Raspberry Pi projects usually are.
According to Neythen, the project was tested and proved to work with a Raspberry Pi 4, Raspberry 3 A and even a Pi Zero (albeit with some latency). There are plans in the works to upgrade the project with text input support.
