Odile’s robot was made of Lego, white Lego exclusively, with some odd number of black-tired white plastic wheels underneath, and what she assumed were solar power cells screwed across its back. She could hear it moving patiently, however randomly, across the carpet of her room. Could you buy white-only Lego? It looked right at home here, where lots of things were white. Nice contrast with the Aegean-blue table legs.
