yeah, I've been there before, it's pretty cool. Even if you have a different body frame, you can get some idea of what you might look like. Good inspiration!
that makes me realize (or re-realize, because I've noticed this before) that I have NO concept of my size. I still see myself as much bigger than I am... the photo at 180, which is just above my start weight, is really how I still tend to see myself. Cool site.
