Download the Arduino sketch for the EEG costume cap here:

To create animating patterns for the cap, the pixels are organized into groups based on where they are on the cap, with a new array for each row, listing the pixels in order from front to back.

int R1[] = {25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35};
int R2[] = {24, 23, 22, 21, 20, 19, 18, 17, 16, 15};
int R3[] = {7, 8, 9, 10, 11, 12, 13};
int R4[] = {6, 5, 4, 3, 2, 1, 0};
int L1[] = {46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36};
int L2[] = {47, 48, 49, 50, 51, 52, 53, 54, 55, 56};
int L3[] = {64, 63, 62, 61, 60, 59, 58, 57};
int L4[] = {65, 66, 67, 68, 69, 70, 71};

With each row in it’s own array, you can code up a for loop that steps through multiple arrays at once to create a racing stripe effect.

void flowingStripes(uint32_t c, uint8_t wait) {
for(uint16_t i=0; i<11; i++) {
      pixel.setPixelColor(R1[i], c);
      pixel.setPixelColor(R2[i], c);
      pixel.setPixelColor(R3[i], c);
      pixel.setPixelColor(R4[i], c);
      pixel.setPixelColor(L1[i], c);
      pixel.setPixelColor(L2[i], c);
      pixel.setPixelColor(L3[i], c);
      pixel.setPixelColor(L4[i], c);
      pixel.show();
      delay(30);
  }
}
