A certain program called 'Animation Master' by Hash Inc., has been doing patch-based modeling from it's inception. A:M uses a patch modeling method that's more akin to Bezier curves than NURBs. Mathematically, they are related since B-Splines are just a generalization of a Bezier curves but the differences presents itself in how we interact with/manipulate them.
The following are links to organic models created with A:M and while they are far from the quality seen in Jinwoo Lee's works, these are done (mostly) by non-professionals and some are actually quite good (note links tagged with a WARNING):
A modeller named Teyon (Alexander) used to do a lot of organic modeling using Rhino. Nowadays, he prefers to use Silo but samples of his earlier work still exists out on the Web - I suggest using Google to find some of his earlier (NURBS-based) work. At one point, Teyon even discussed his workflow and I remember being shocked at the limited number of commands (from Rhino) that he uses to get the results he was getting.
