It's always interesting to me what people consider
to be "easy" problems. But "here are a bunch of
3D points with no seeming relationship to one another,
so I want you to connect them up into something I might
recognize" seems pretty hard to me. :-)

I mean if you have 100 points, there must be nearly
!100 ways to do it wrong!

Cheers,

David
