Looking For ???

Okay, I'm sure I've seen one out there somewhere ... Does anyone know where I can find a (free) graphic thing to put in my sidebar to show the progress on my weight loss? I'm 99% sure that I saw one on someone else's blog months and months ago, back before I realised just how large my ass had grown over the winter, and now it's bugging me because I'd love to have one on mine! I've been scanning back over blogs I haven't visited in months, but no luck.

Help?
