Breed Customizable 4x Leash Hook

I wanted to make a hook to mount near the door to hang the dog leash, my keys, and a "paw towel" on. I have a cute little pug named doughnut and I thought it would be cool to put a little pug silhouette on it, but then I thought that this might be a good opportunity to utilize the Makerbot "customizer" app for people with other breeds.
I am very new to OpenSCAD, the only other thing I have made is a customizable little tube. However, I am always eager to learn so I started doing some research. I was looking for a way to draw the silhouettes when I stumbled upon dnewman's "Inkscape to OpenSCAD converter v2". http://www.thingiverse.com/thing:25036
Perfect! I simply vectored my silhouettes in illustrator and used dnewman's Inkscape extension to convert them to .scad.
I am sure there is a better way to make the "options" then the way I did it (feel free to post in the comments).
