Many thanks to Benni for hosting this week. A great theme, one I don't think we've had before!! Lots of possibilities here!!
Here are mine:
1) One of the commonest twists, seen in many many places.
2) I call this one 'The Wriggly Tree'
3) This is the ceiling of the 'Y Synedd', the Welsh Assembly building, Cardiff, Wales.
4) Let's twist again...........
