I needed a list of CSS showcase sites for a buddy of mine and for my future reference – from my bookmarks, delicious and Google – this is what I came up with –

• http://cssmania.com/
• http://www.cssbeauty.com/
• http://cssvault.com/
• http://www.cssremix.com/
• http://www.cssshowcase.co.uk/
• http://www.cssbloom.com/
• http://zeniltuo.com/
• http://www.cssbased.com/
• http://csszengarden.com/
• http://www.stylegala.com/
• http://www.cssclip.com/
• http://cssprincess.com/
• http://www.designshack.co.uk/

Any more to add?
