I know that this has been done many times before but I thought that as Firefox now supports CSS3 3D transforms I would revisit it and put my 'twist' on this.

So not only does the box spin, it also has the images on each face rotate.

I have also found a way to partially fix the 'jagged' edges of the 3D faces in Firefox. This just requires a 1px box shadow with a little transparency '-moz-box-shadow: 0px 0px 1px rgba(0, 0, 0, 0.5);'.
