PiazzA Theme is for the new CM Theme Engine introduced in CM11.
You will need to have a custom Rom that supports the CM11 TE installed on your phone or tablet.
CM11, PA4+, and AOKP are some examples of the custom Roms.
The main focus of PiazzA is to be square. ;)
A lot of icons have been Piazza'd. Over 900+ and more to come.
What has been themed in Styles so far?
Google News and Weather
This theme will grow in icon support.
But to do that, I'll need your help.
Please goto the PiazzA Theme Community on Google+ if you have an icon not Piazza'd.
Thank you for your support and I hope you enjoy PiazzA.
