Notices: Each pixel is 1 wide and 2 high and the default pixel selector is reversed, so the left side is the right side, etc.

My Observer Display is one of my best projects. It is a fully functional display using observers. Now, when I say this took me a long time to build, I literally mean this took me AGES to build. I'm new to this kind of stuff, so please don't judge.

Using it is pretty easy... Just flip the lever and a pixel will change.

This works by using a basic pixel selector that runs into a piston which touches next to an observer block, which detects a block update. It travels down a line of observers and then gives a 1-tick pulse to a sticky piston, which moves one pixel forward a block.
