  +== Color Parameters
   
   Color parameters are an extremely flexible way of dynamically assigning
   color. The basic way to create one is to call:
  
positive.code: 
  As an example of using these parameters, consider:
  
  code,clojure---------------------------------------------------
  code,clojure
  (afterglow.effects.params/build-variable-param :key
    :type Number :default 0 :adjust-fn #(* % 2))
  ---------------------------------------------------
  
  This would cause the dynamic parameter to have a numeric value which is
  twice the value found in the show variable.
  
negative.code: building another dynamic parameter, the type and default are assumed
  from the context in which you are using the variable.
  
  == Oscillated Parameters
  
  Oscillated parameters vary over time, at a speed controlled by a
  <<metronomes#metronomes,Metronome>> (usually the main show metronome,
  synced to DJ equipment) and so can make the lights appear to be
  reacting intelligently to the music being played. The timing
  information produced by the metronome is fed into an
  <<oscillators#oscillators,Oscillator>>, which determines the shape of
  the wave that controls its value, and the frequency at which it
  oscillates, related to beats, bars, or phrases of the underlying
  metronome. The resulting value can then be scaled to meet the needs of
  whatever is being generated (a dimmer level, color component, or light
  rotation). Oscillated parameters are created by calling:
  
  [source,clojure]
  ----
  (afterglow.effects.params/build-oscillated-param oscillator)
  ----
  
  The `oscillator` parameter is an
  <<oscillators#oscillators,Oscillator>> created by one of the functions
  in
  http://deepsymmetry.org/afterglow/doc/afterglow.effects.oscillators.html[afterglow.effects.oscillators]
  which, as described above, determines how to react to the time
  information provided by the metronome. Additionally, you can supply
  one of the following optional keyword parameters:
