Need mod to display custom changes on product
 

This is probably a big order, and I am still shopping other shopping carts but right now I have xCart, so a module/add on would actually be my best bet - if something like this exists.

I need to be able to display a sample product and then allow my customers to add text/font in different areas, AND have it display on the screen. I can set up variants to provide the color options, but so far, no way to allow them to play with text and place it where they want it.

Any ideas?
