Decorative Usage
USB decorations may have no useful functionality other than aesthetic ornamentation. For example, lights, lighted cables, displays, miniature disco balls, aquariums, terrariums, waterfalls and pole dancers are all available in USB-powered versions.
Arguably, there are many USB-based decorations embedded in existing products—keyboards with impractical backlighting (such as ones that only turn on while pressing a key, and ones that flash to the beat of a song), mice that (when the computer is turned off) turn on/off their light to a pre-programmed beat, or printers that show random quotations on LCD screens when not in use.
A similar concept exists in the form of decorations that are powered by car adapter plugs. USB adapters for automobiles (and built-in USB ports in newer models) can also power USB decorations. Some USB devices can even be jury rigged to work on 12 volts with a simple resistor, in which is the electrical opposite of converting a light-up ornament to a DIY USB decoration.

Famous quotes containing the words decorative and/or usage:
“A man may lack everything but tact and conviction and still be a forcible speaker; but without these nothing will avail.... Fluency, grace, logical order, and the like, are merely the decorative surface of oratory.”
—Charles Horton Cooley (1864–1929)
“...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
—Kenneth G. Wilson (b. 1923)
