const uint8_t ppm = 150;  //pixels per matrix


//You can do something like this to simply copy the data to the other matrices as the first matrix is filled in.

for (uint16_t i=0; i<ppm; i++) {
  leds[i] = CHSV(random8(),255,255);

  // copy to other matrices

Another option (that uses a bit more memory) is to use a second array (let's call it leds_display) that
you copy your leds data to with the offset before displaying.  So it the top of your program you will
have two CRGB arrays:

CRGB leds[NUM_LEDS];  //working array
CRGB leds_display[NUM_LEDS];  //array that gets displayed

Copied here since G+ is going away.

When using fill_rainbow...

To make the rainbow flow go the other way you can multiply the millis bit by -1:
change this:
fill_rainbow( leds[x], stripLength, millis()/2, 256/stripLength );
