The Roulette Wheel part is really interesting.

I've never used your 'blend' method to intersect a circle.
That's really, really interesting.
Gonna give that a go, for sure.

OK. A bit of math is involved, so, I'm gonna see if my method of just cloning and rotating, and cloning and rotating, and cloning and rotating (you get the idea!) is easier or is it worth working out what you want to achieve and then doing that in one go.
