Customized Cartoon with PHP & GD (and job offer)

I would like to do a 'customized single pane cartoon' with PHP and GD. What I would like to happen would be for the web visitor to be able to select the two characters, their clothes/hair/skin color/glasses along with the sun/rain/snow and then be able to put a bubble for the text of each of the characters. Then output the image to the browser in a separate window. Has anyone done that yet ? From my initial calculations, I would have close to 2,000,000 possible combinations. Something like: http://www.thebench.org/index.php3?strip=2066 but all done online. [job offer] If anyone has done anything like this, please email me so that we could discuss cost/payment on a similar type of project. [/job offer] Paul
