check this example and I liked it but I see no barrier to grayscale if not that white fencealpha
this is the example
float increment = 0.01;
// The noise function's 3rd argument, a global variable that increments once per cycle
float zoff = 0.0;
// We will increment zoff differently than xoff and yoff
float zincrement = 0.006;
void setup() {
size(800,600);
frameRate(30);
}
void draw() {
background(#F51941);
// Optional: adjust noise detail here
// noiseDetail(8,0.65f);
loadPixels();
float xoff = 0.0; // Start xoff at 0
// For every x,y coordinate in a 2D space, calculate a noise value and produce a brightness value
for (int x = 0; x < width; x++) {
xoff += increment; // Increment xoff
float yoff = 0.0; // For every xoff, start yoff at 0
for (int y = 0; y < height; y++) {
yoff += increment; // Increment yoff
// Calculate noise and scale by 255
float bright = noise(xoff,yoff,zoff)*255;
// Try using this line instead
//float bright = random(0,255);
// Set each pixel onscreen to a grayscale value
pixels[x+y*width] = color(bright,bright);
}
}
updatePixels();
zoff += zincrement; // Increment zoff
}
