Has anybody seen a body size simulator?

Was looking to see if any of you have seen a website where you can view a simulation of a desired body size or type. Basically I'm looking to put my headshot on my goal weight/size type figure to help motivate me. This would be very similar to one of those hairstyle sites that allows you drop in a headshot and allows for different hair styles and color.
