// This example combines two features of FastLED to produce a remarkable range
// of effects from a relatively small amount of code.  This example combines
// FastLED's color palette lookup functions with FastLED's Perlin noise
// generator, and the combination is extremely powerful.
//
// You might want to look at the "ColorPalette" and "Noise" examples separately
// if this example code seems daunting.
//
//
// The basic setup here is that for each frame, we generate a new array of
// 'noise' data, and then map it onto the LED matrix through a color palette.
//
// Periodically, the color palette is changed, and new noise-generation
// parameters are chosen at the same time.  In this example, specific
// noise-generation values have been selected to match the given color palettes;
// some are faster, or slower, or larger, or smaller than others, but there's no
// reason these parameters can't be freely mixed-and-matched.
//
// In addition, this example includes some fast automatic 'data smoothing' at
// lower noise speeds to help produce smoother animations in those cases.
//
// The FastLED built-in color palettes (Forest, Clouds, Lava, Ocean, Party) are
// used, as well as some 'hand-defined' ones, and some proceedurally generated
// palettes.

// Scale determines how far apart the pixels in our noise matrix are.  Try
// changing these values around to see how it affects the motion of the display.
// The higher the value of scale, the more "zoomed out" the noise iwll be.  A
// value of 1 will be so zoomed in, you'll mostly see solid colors.
#define SCALE 20

// We're using the x/y dimensions to map to the x/y pixels on the matrix.  We'll
// use the z-axis for "time".  speed determines how fast time moves forward. Try
// 1 for a very slow moving effect, or 60 for something that ends up looking
// like water.
