Yet another shape.

These are some great tests I must say - they really get you to think nurby-nurby!

As Michael said, I'm seeing a sphere with a portion of the surface extracted - the edges however sound like a loft or something dealing with a profile.

The indentations seems to me look like they should be created seperately (using circles of differing levels and perhaps a profile curve used as a 2-rail sweep? This is then somehow boolean'ed or blended onto the main surface (definitely not sure of that one?)

Figuring this one out would definitely be a great lesson!
