Gorgeous geometry.. think this would probably be a 3 star today though, grade inflation is quite the thing!

I see that when this was featured on CTC four years ago I failed to solve it, so it's nice to know that four years of doing sudoku every day has had some effect. Even second time round it was tough going though. Thanks.
