It's fan art... of FAN ART.
Makani is AMAZING. And she doesnt' update NEAR enough.
But her design for The Announcer for TF2 is generally the accepted one among fans. :>
And her drawings of an anthropomorphized GLaDOS are pretty rad too.
WELL if you don't get it by now I'll just tell you WHY THIS IS FUNNY:
GLaDOS and The Announcer are voiced by the same person, and while not readily noticeable, I was definitely picking up vibes when playing Portal.
Ellen McLain is. a. GENIUS.
