Looks like my oven hob. Very good puzzle and approachable if you are good at maths. Clever use of constraint types and pleasing on the eye.

Tricky break but incredibly elegant, then followed by a super smooth solve

A suprisingly approachable puzzle from Kaktuslav. Pretty and quite easy after the break-in.
