ookami-kun (http://www.furaffinity.net/user/ookami-kun) went for the Portal theme in this commission, drawing Rooth as an Aperature Science test subject. Perhaps this is how he acquired his first Portal Gun? :)
Ookami-kun has a pretty neat style. Her way of drawing Rooth's face is pretty sweet. It's one of the more humanistic interpretations (though not as much as fydbac does), but it's perfect for the style and form.
Also, glowies rock. Just saying. >.>
