I participated a while ago in Smashing Magazine CSS3 Contest.

The aim was to play with CSS3. So I used my non-talent to design a menu enabling actions on a content, without Javascript. I used the general sibling selector ~, pseudo class :active,  and some other well know stuff, such as border-radius and transform.
