So-Not-Russian Nesting Gourds

I have a confession to make. I have always wanted a set of Russian Nesting Dolls. Why, you ask? Well, I can't remember when the obsession started, but I do know it goes way back. I can't remember a time when I didn't love these cute little pieces of carved wood that, when opened, revealed a smaller replica of itself inside. I think it's the genius design that gets me. The adage "form follows function" comes to mind, except they are completely useless aside from being decorative. None the less, I have lusted after what I see as an object that still stands today as an example of great design.
So why I have never bought myself a set is perplexing. Perhaps I have been waiting for a trip to Russian to treat myself to an "authentic" one.
Well, my wait ended when my girlfriend Rebecca, upon discovering this obsession, took it upon herself to end my wait. Brilliantly, she opted for a modern, abstracted version of the classics. I call them my So-Not-Russian Nesting Gourds. My favorite is No.2, with it's pretty little polka dots. Which is your favorite?
