Progress Meters

progress_metersAlthough this is more of a gigantic bookmark for myself, I came across a cool set progress meters for use on buttons. Some are quite “flat” in their design, and others will use a neat 3D effect to show the progress meter on the edge of the button. All of the meters will animate smoothly, although the pages does indicate that “Without support for transform-style: preserve-3d you will see the fallback style (fill horizontal).”
