John Schulz continues to do my job for me.

re: putImageData is a complete jerk I don’t know if this has been suggested already, but use drawImage instead http://jsfiddle.net/JFSIII/Ga5jf/

The thing pulling it all together is converting the canvas into a data URL and using that as an image:

var img = new Image();
img.src = canvas2.toDataURL('image/png');
ctx2.drawImage(img, 30, 10);

Gonna have to give him a back rub one of these days.
