@samjshah2 @Gelada @zacharyabel ahhh, so sorry! I actually made the image data for the en-primed version, but that's the original. Hang on...
@samjshah2 @Gelada @zacharyabel Here you go. Not quite as nice this time. It seems to occasionally get lucky and find a prime without changing too much, and other times messes things up. I'm sure I could apply some simple divisibility tricks to the last few digits to make it quicker
@samjshah2 @Gelada @zacharyabel ah! It found this one after only changing 104 pixels. That's pretty much ideal
