-14. Background Animations
+14. Backgrounds
 ************************************************************
 StepMania supports three different modes of backgrounds:
 BGAnimations - The background will cycle randomly through different sprite 
 animations.  Each of these animation must reside in the "BGAnimations" 
 folder in the StepMania program directory.  See the section called 
 "BGAnimations" in the readme for more information on the BGAnimations format.
 BGAnimations will perform better than the other background modes on slower 
 computers.
 Random Movies - The background will cycle randomly over any avi or mpg files 
 in the "RandomMovies" folder in the StepMania program directory.
 Visualizations - A random avi or mpg file will be chosen from the 
 "Visualizations" folder in the StepMania program directory.  This movie file 
 will be played and blended over top of the song's background graphic.
 Many video AVIs will require the DivX codec for playback.  If you haven't yet
 downloaded DivX, you can get it from www.divx.com.  Playing movies as the 
 background is very processor intensive, and may cause the frame rate to 
 decrease on slower computers.
 Sample animations, visualizations, and random movies can be found at 
 www.stepmania.com.
 ************************************************************
 15. BGAnimations Format
 ************************************************************
 The BGAnimations folder in the StepMania program directory may contain several
 BGAnimation folders.
 \BGAnimations\<anim folder>\<layer files>
-Why?
+<anim folder> is the name of the animation.
-Grouping all of the graphics for an animation into one file would be a pain.  If you want your sprites to have animation and you put all the frames for multiple animations into one big graphics file:  a) That file would be huge and many video cards can't draw large textures, b) You'd have to create some other text file that says which frames of the graphic belong to which sprite, c) If your sprites are different sizes, there will be a lot of wasted space between the frames of that graphic, and d) It's a pain for the artist to cut and paste a whole bunch of frames from different animations into one graphic (and make sure everything is lined up right).
+<layer files> are one or more graphics files that will be used as layers in the 
 animation.  Each sprite represents exactly one layer.  Multiple layers can be 
 specified by having multiple <layer files>.  
-The BGAnimations folder should contain several folders for individual background animations.  Currently, these background animations cycle in order of their folder names, changing every 4 measures of the song.
+For example, a BGAnimation named "flower" may include the files:
-In an animation folder, each sprite represents one layer.  Multiple layers can be specified by having multiple sprites.  Layers are drawn from back to front in order of their file name.  Different "layer effects" are specified by adding tokens to the file name.  Here are an explanation of the currently supported tokens:
+	BGAnimations\flower\1 TileScrollUp.png
 	BGAnimations\flower\2 StartOnRandomFrame ParticlesFloatDown 1x2.png
 	BGAnimations\flower\3 TileScrollLeft CycleColor 2x2.png
-usesongbg - Use the song's background file instead of this graphics file.  Since this graphics file will not be used, you might want to make this graphic a 1x1 graphic to save space.
+The first number in the name of a <layer file> will specifies its drawing 
 order.  A layers with a small number will be drawn before a layer with a larger
 number.
-add - use additive blending instead of normal blending.
+Different "effects" are specified for each layer by adding tokens to the file 
 name.  Here are an explanation of the currently supported tokens:
-cyclecolor - cycle the color of the layer over the colors of the rainbow
+UseSongBg - Use the song's background file instead of this graphics file.  
 Since this graphics file is merely a placeholder, you might want to make this 
 graphic a 1x1 graphic to save disk space.
-cyclealpha - cycle the alpha channel of the layer over type
+Add - use additive blending instead of normal blending.
-startonrandomframe - Start the animation on a random frame.  This is mainly useful for Tile or Particle effects.
