I managed to get processing.js - a javascript based processing clone - to run in an apple dashboard widget.

to make one your self fire up dashcode, and add processing.js and add an canvas element to the widget

then add it in the header of your html file

<script type="text/javascript" src="processing.js" charset="utf-8"></script>

add an script section to your html file containing the processing code to the body tag

<script id="code" type="application/processing" charset="utf-8">
int x = 25; 
int y = 25; 

int dx = 4; 
int dy = 3;

void setup() { 
    size(300, 300); 
    frameRate( 25 ); 
} 

void draw() {
    x += dx; 
    y += dy;
    if ( x > width - 25 || x < 25 ) { dx *= -1; } 
    if ( y > height - 25 || y < 25 ) { dy *= -1; }
    background(0);
    fill(255); ellipse(x, y, 50, 50);
}
</script>

and finally add this code to the "show()" method of your javascript file

var f = document.getElementById("code");
Processing(document.getElementById("canvas"), f.textContent );
