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 Support.

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