Day 3: the Generator (#3). This cell takes the cell that's behind it and creates a clone of it, pushing whatever's in front of it to make space. Unlike the Mover, it doesn't have bias, and certain cells can't be generated by it.
I think I'm understanding the shading a little more. This guy has more overlapping pieces and sharp corners so I had to get a little creative, especially with the tiny pixel art form. I imagine that it would clone the cell by poking it with the tip of its tail, and it would shoot out through the diamond at the front. That or it spits the clone out. Both options seem probable.
