well since you posted this in the nurbs section. try looking up patch modeling in maya on google or yahoo. The currnt trend is using displacement maps btw. Best used with polygons or sub-d's. If your going for a lower poly look, mtmckinley had a good one posted for building his digital self I think (if it's not mike, sorry. when I visualize you all i see is that big dude with the big arms and black beard, to tell you the truth i would be hard pressed to say that you yourself weren't just an Alias/Wavefont construct. LOL, something like out of the matrix.) Enough rambling. Also, look in the Simplymaya Tutorials section. I'm sure there are things there.
And after calming me down with some orange slices and some fetal spooning,
E.T. revealed to me his singular purpose.
