DarkFlow is Unique Set of Icons with a Dark-Accent Palette. This is what Dark Material Design would have been.
Though it doesn't follow all the Material Guidelines it gives a perfect Material look.
Each icon is crafted uniquely and originally.

Features:
800+ Icons.
20 HD Cloud Based Wallpapers.
Compatible with most of the major launchers.
Stock Icons for Asus, Cyanogenmod, HTC, LG, Samsung, Sony Xperia and Moto.
Muzei .

DarkFlow is in its early stage, so there are some app yet to be themed.
Please be patient.
