We screwed the part that connected to the seat of the chair into the ceiling of the room. we painted a black and gray "Rail" around this piece to convey Wheatley's rail.
AND YOU ARE DONE!!!! Go admire your Wheatley model while playing your favorite video game. Testing will never be dull with this exciting little guy in your room. He may be an idiot, but he will be your best friend. (Other than the companion cube, of course)
This model can also be used to make any of the Personality Cores from the game Portal 2 just by coloring the LED light differently.
So what are you waiting for? Go make yourself a great Wheatley!!!
