I was watching this video the other day http://www.youtube.com/watch?v=HzJKae7HcZY&list=FLbbQ_ZKcMFq4YgGyxoY3p_Q&index=1&feature=plpp_video , that showed early concept art and animation tests for what GLaDOS would look like in Portal 2. One of the ideas they had was that she would be so damaged after Portal 1, all that was left of her was a head on a wire. I couldn’t help thinking what an android version of this would look like. I think the results would be kinda disturbing. I don’t usually draw things like this, but it was pretty fun. The link there is actually the last part of six videos of a presentation Karen Prell did at Animex. If your interested in seeing some of the ways they made Portal 2 you should really give the other videos a watch, they’re pretty neat.
