Here's as good a place as any to link to my many many MANY free skins that I've created over the last few years, and some that I've fixed up and put elsewhere. 

It's from the DesignAway skin which I created for a competition and it's been very popular over the last couple of years, not just the look of it, but great to learn from.

You can view the skin set http://www.ninasfreeskins.com/designaway/vertical-menu.aspx 

Registered users can download it from Here

It is using the solpart menu functions and you should be able to view the CSS file and learn from it.

This has been quite a popular design - and you can see the whole skin set http://www.ninasfreeskins.com/designaway/home.aspx

Over the coming weeks I will attempt to get all the skins I have for download online here, they are in different places for different reasons... and as I put them online, you can preview them as well before choosing whether you want to register and download them.

Enjoy!
