From Tim van de Vathorst:
The moment I realized the my Christmas LED Panel experiment was a success, I wanted to take it to the next level. My goal was to see People draw on my LED Panel in real time. I decided to add a clock. After 1 minute of inactivity, a clock will show up on top of the drawing.
You can now draw on top of my clock, with multiple people, and it will show up in real time in my house!
