Can't display changing matrix of rectangles using delay

Hi guys,
I'm new to Processing. Why don't I see the first matrix drawn? I seem to only see the matrix after the delay, and not the one before. My ultimate goal is to watch how a matrix changes over time steps.
// Number of columns and rows in the grid
int[][] myArray = { {0, 1, 2, 3},
{3, 2, 1, 0},
{3, 5, 6, 1},
{3, 8, 3, 4} };
void setup() {
size(200,200);
}
void draw() {
background(204);
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
rect(20+30*j,30+30*i,3,3);
}
}
delay(2500);
background(204);
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
rect(40+30*j,50+30*i,7,7);
}
}
}
