I was just noticing that.

Mapping must happen at 0, I tend to overlook. Went thru the spherical and was
noticing everything you said, now cylindrical works, I'm just a little slow at
catching on. One day I remember mapping happens a ZERO, DOH.

These were done done with spherical density pattern which seems to be faster
than cylindrical.

Scaling a sphere would get you lenticular or lens shape:
