New theme to celebrate 266HD ! I used a 266 collection for a long time, happy that now it's out for retina.
To have the same result, hide everything (status bar, statusbar icons, battery, etc), with springtomize, and go into Theming to change opacity (I put the slider just after the "transparency" word).
Included is a iconoclasm layout I made, it's a slight modification of the standard 5*5. Put it in library\iconoclasm\layout
