To celebrate the 65th anniversary of our university, I created a website that simulates a screen through windows.
The original image is only half the size which is too small, so I copied and horizontally flipped it to make it double size. I cropped two sizes of windows, and the final resolution is 20x14 which is enough to fit some pattern.
I also used socket.io to make it real-time. This means if a person toggles a pixel, the change will also appear on any other people's site. This resembles the real-life when multiple people are drawing on the same art board.
Here are some examples that show what it can make.
