Oops.
Well actually it seems Pixar has the right to use the lamp in movies (and yes, technically their logo - I just thought the above illustration was amusing) but they don't have the right to go out and make lamps.
Lamps?
You know, like the Blu-ray version of Up with Limited Edition Luxo Jr. Collectible Lamp:
Aaaah.
Disney also made a Luxo Jr. character for Walt Disney World, too.
