The code below generally gives an OutOfMemoryError within a minute in Processing 1.0.1
under Mac OS 10.5.5 on a 2.6GHz/4GB Mac Book Pro, running in the default memory
configuration (and also in increased memory configurations, though possibly more slowly). I'll
include the full red error message below the code.

The error occurs when using either rotateX() or rotateY() (or both), but rotateZ() seems to
be okay.

I also get the same error if I switch to OPENGL (and then it also looks worse).

void setup()

noStroke();
}

void draw()
{
rotateX(random(2 * PI));
//rotateY(random(2 * PI));
//rotateZ(random(2 * PI));
fill(random(255), random(255), random(255), random(50));
ellipse(random(width) , random(height), random(200), random(200));
}

--- error message ---

An OutOfMemoryError means that your code is either using up too much memory
because of a bug (e.g. creating an array that's too large, or unintentionally
loading thousands of images), or that your sketch may need more memory to run.
If your sketch uses a lot of memory (for instance if it loads a lot of data files)
you can increase the memory available to your sketch using the Preferences window.
