I'm a big fan of themes, especially ones that use the CM7 Theme Chooser. In my search for some nice, monochromatic themes, I've stumbled upon one called JAMT - Flat Black.
JAMT Black is more of a notification bar and volume slider theme than anything else. None of the icons get themed, but sliders are now rendered a nice, monochromed grey.
In addition, the notification bar gets a few new notification icons (the most prominent of which is the Gmail icon). The wifi icon is also transformed into this strange, curvy-looking set of bars as opposed to the straight, vertical lines we're probably accustomed to, but outside of that, the biggest change would be the icons on the notification widget.
There's also a bit of theming on the toast notifications, changing their background to pure black and with sharp corners instead of rounded edges. It's another nifty piece of eye candy, especially if you like the hard edges of the Droid line.
Best of all, this theme is completely free in the Market with a donate version for $1.00. If you like what you see, we've got more pictures download links after the break.
