My previous spiral clock images generated with Mathmap are now available at Getty Images. The bad news is that they are now copyrighted.
However most of the hits I got were from blogs that use them. So I created some new ones, licensed under the creative commons license, some animated for use in your personal blogs. You can see the animation in the first comment.
Have fun using them. I appreciate if you link to the place of use with a comment but it is not a must.
To post this one the website, just grab the html code of the original image, you can find it next to the email and Facebook drop down on top of the static image.
This clock might take some time to get visible on your website, so you can find a lighter version with only one pointer here:
And a static one here:
