  As mentioned above, there are a number of ways to combine these
  effects. If you have a group of effects that you want to start and
  stop at the same time, you can group them into a <<scenes,scene>>. To
  smoothly transition from one effect to another you can use a
  <<fades,fade>>, and either side of the fade can be a scene. Or you can
  fade to or from a <<blank-effects,blank effect>>, or sequence a whole
  list of effects or scenes using a <<chases,chase>>.
  
  <<conditional-effects,Conditional effects>> and
  <<variable-effects,variable effects>> are designed to make it easy for
  effects to influence and interact with each other by responding to and
  setting show variables. Finally, Afterglow includes some examples of
  how to build up <<complex-effects,special-purpose effects>>, which can
  be fun in themselves, and also serve as templates and inspiration for
  whole new kinds of effects you create on your own.
