This is a sculpture of POTaDOS, or GLaDOS from Portal 2 when her mind is implanted into a potato battery.
I made it out of Sculpey clay, wire, alligator clips, nails, two rubber bands, acrylic paint, and Sculpey glaze.
Took a hell of a long time to make.
Here's the Etsy page if you want to look at more pictures, or even purchase it if you're interested. [link]
