A long long time ago I had a fun time making Mobius strip structure out of link list(s).

Each edge of the ribbon was a linked list, connected to each other by rungs. It looped back on itself but connected crosswise .

Then if you nuked all the rungs it was clear you still got a connected piece that you could traverse over.

Interesting article. Note that many of the clues in the article are mis numbered.

Not sure why. Refer to the original puzzles linked for the correct clues.

My partner publishes crosswords and it's always fun to see how much artistry goes into authoring a puzzle. You can play with the structure/grid, the theme of course, every minute detail of the fill, etc.

Never would have thought of a Mobius-strip though, insane.
