12x12 Ribbon Tour

This 12x12 knight tour with 180 degree rotational symmetry completes the set of ribbon tours constructed over the last few days, the others being on boards 18x18 and 24x24. I've also been showing them on Twitter. 



Also shown here is the well known 6x6 tour of similar design. This like the 18x18 tour has 90 degree rotational symmetry.
