Did the Marbling Infinity Puzzle from Nervous System on a short vacation. Lots of fun and rather challenging for 180 pieces.
In case you haven't seen this cool idea, the picture wraps around, so the pieces on the top edge can be taken out and reconnected at the bottom etc. I.e. the pieces would fill the surface of a torus if they were floppy enough?
It means the way we finished it could (and almost certainly will) look different from the way others will complete it.
Thanks @nervous_jessica
