The white squares in the lower black half are getting black in the upper white half like in a mirror changing everything white to blach and black to white. I hope, it´s not too easy now!
Another nice puzzle, Hans Peter! With all of these new puzzles lately, I find myself searching for the ones that say "inverse." I know they'll be fun challenges with a rewarding picture at the end. Thanks!
