I made progress bars using only CSS3. You can use them for free.
I'm not sure how these are innovative at all as it's just three Div's and some CSS. Yes it does use CSS gradients and box shadows to look a little nicer but this is realy something that can be whipped up in a few lines of CSS. Does it realy warrant a GitHub project? It would be better as a tutorial showing others how to make it from scratch.
