Seen many times at a gym I lift at, Crossfit Greenpoint, I see many sporting a hairstyle of too much hair. Aspiring Samurai warriors want to know. I am likely just having Hair hating envy. Hipsters of Greenpoint and Williamsburg in their glory.

My manikins in the Simlab don't have developed ears hence can't place those n/c in the traditional method. Hence practiced this n/c technique on this blessed pieces of plastic and rubber.
