Random Rotating Pattern

I want to make a rotation pattern and combine it with the random function to make a random rotating pattern. So here's the first step, pasted both the "random" code and the "rotation" code,
and replace the dinoimage with a photo of a painting. I shrunk it to 75 x 100 pixels and uploaded it to photobucket for ease of use and transfer between computers.

I also notated the random code (which works, by itself).
****************************************************************

/*void setup()
{
int a;
float x,y; //random function returns a float (a number with a decimal point,) so we must have float vars

size(800,800);

PImage abstract1; //create an image object
abstract1 = loadImage("http://i84.photobucket.com/albums/k25/Stickchair68/abstractmini.png?t=1296774852"); //set source file

for(a=0;a<100;a++)
{
x=random(0,726); //keeps everything inside the window, no running over
y=random(0,700);
image(abstract1,x,y); //draw images at random points
}
}
*/

//Figure out how to rotate things in 2D in Processing

void CartoonFace(float x_coord, float y_coord)

ellipse(x_coord-20,y_coord-20,30,50);

size(500,500);
background(255,100,0);

x=width/2;

//---------------------------------
pushMatrix(); //load all the pixels in the window into a transformation matrix

translate(x,y); //move the matrix to the middle of the screen
rect(0,0,100,100); //draw a rectangle into the matrix
rotate(radians(45)); //rotate the matrix

stroke(0,255,255);
rect(0,0,100,100); //draw another rectangle into the matrix

stroke(0,255,0);
CartoonFace(0,0); //draw our cartoon face into the matrix

popMatrix(); //unload all the pixels from the transformation matrix
//-------------------------------

stroke(0,0,0); //we are off the matrix and things are back to normal :)
rect(0,0,100,100);
CartoonFace(0,0);
