As John Gage writes in "Color and Culture" (Bulfinch, 1993), countless attempts have been made to systematize language about color: color wheels, color spheres, color spectrums.
"How did you go up?" She glances at Margaret Bowman, sitting at the neighbouring potter's wheel, whose clay sphere is showing definite signs of rising between her fingers.
Dyson's solution was to design a deep molded-plastic trough and to replace the wheel with a plastic sphere.
But when the lighting brightened, and the sphere was wheeled into full view and spun around, it rattled and suddenly looked sadly makeshift, like some huge drably painted Whiffle Ball.
Collectively, these squeaky wheels in tweeter-sphere were like a screeching crescendo of scratchy noises.
The concept map is colour coded according to the traditional colour wheel with redder or 'warmer' spheres being where the more frequent concepts are likely to be found and bluer spheres being where the least frequent concepts are more likely to be found.
The Silhouette Sphere's hook is its spinner wheels, or wheels that rotate in all directions.
All these wheel rims had originally been formed out of an original sphere of fire wholly encompassing the Earth, which had disintegrated into many individual rings.
Behind that trilling orange and white sphere, BB-8 is likely a set of wheels (propelling the sphere by spinning against its inner-wall) and a magnetic mast (to hold on to and control BB-8's head).
The plaques of stage IV looked like wheels, with a star-like core linked to a fibrous sphere through several spokes.
Scheduled to go on sale in the summer for about $80, the Terrainiac is a futuristic-looking vehicle powered by a single rear wheel that is a complex treaded ball, referred to by its makers as a "sphere drive".
