Well, I never did anything small or, I should say, easy. Most folks take a tutorial and follow it when they're learning a program but that's not what I did for learning Rhino. I took a tutorial for making a wine glass and made something completely different. A creature's head. Ugliest thing I could think of to make. I even textured it...sorta. Thing is, it was something no one had really used the app for before, so everyone was in awe. Now it's more common but yeah, that was my first.  I've been modeling creatures and characters ever since, moving from NURBS to Polygons/Subdivison Surfaces.
