Krista M said she like my status images over on the side bar, and asked where I got them. I made them myself in GIMP. Here is a guide on how I made them. It assumes a little familiarity with GIMP, but not much. Hope you find it helpful.
Summary: Create an image in GIMP having 1 layer for each percentage step. Mark only the layers that you need for a given percentage as visible and save as gif/jpeg.
Also, I am going to attempt to make a Google Gadget that will allow you to use custom images for status tracking. But I can't make any promises about it.
