Very nice one, Richard! This puzzle gave me an idea and I think I am going to do it just like cam. :-)

@Phistomefel: you are more than welcome! :-) Fortunately sudoku types are not copyrighted, otherwise SVS would only contain less then 15 episodes!
Looking forward to your creation. ;-)

@panthchesh: Your Penpa-implementation of Richard's puzzle is missing a white circle in the crossing R56C67.

@cam: by the looks of it, you didn't wait long indeed! :-) :-)
I am not a great fan of Klein's bottles in sudoku, so I don't think I'll share your enthusiasm vice versa. ;-)
