Ah, computers are wonderful. They are useful for finding useful things. Such as new shoes on ebay and porn. Lots and lots of porn.
But they have been very helpful in my weightloss. You know sharing of info via message boards and finding things to keep me motivated.
That's how I came across my virtual model. Plug in your details (height, weight, skin tone, shoulder width etc) and it comes up with a computerised version of your body.
Old fat me at 126.5kg on the left, and apparently the new me at 91kg on the right (I don't have the definition in the stomach or chest like that but it's close).
You can do all sorts of fun things like dress you up, give massive muscly abs etc.
