This is cool just for fun, but practically there are sites like http://ajaxload.info/ that generate spinners for you, if you don't know how to do it yourself
I tried them and they produced poor quality. They couldn't even get the white background correct! I suppose their #1 ranking on Google is making them complacent.
http://www.loadinfo.net/ is much better presented and actually respects the color values you type in! (And no, I don't have any relationship with them.)
