This was an exercise in dithering, which I'm not quite accustomed to. I started pixelling my source image on both halves, but it was so frusterating that I decided to flip the majority of the image and paste it on the other side.
I discovered that dithering takes quite a lot of patience, which I do not have, so I am never doing it again. |
Looks like CGA... oh wait, 6 colours ? not CGA then.
