Fairly heavily modded G0 Launcher with a customized Matrix background theme.
I can't exactly give instructions on how to install it, moreso than just plug Go Launcher. It has a ton of available community created themes that are inter-mixable, and built-in features that allow you to customize the functionality.
Notification bar is hidden by default; retrieved with an up-swipe, opened entirely with a down-swipe.
Bottom app bar scrolls with 4 total rows.
Red/Black theme to compliment the Droid Ultra Verizon Employee Edition phone that has the red graphics on the back and red buttons.
