I wanted to make a homescreen based around a piece of art, keeping its theme and aesthetic while still trying to make it functional. I chose Wayne Thiebaud's "Supine Woman" as a base, and used UCCW widget to create a homescreen around it.
Launcher: The launcher is the Google Now Launcher. It doesn't let you customize the icons, but that 'Ok Google' function is quite cool. And I use Google Now pretty often, it's useful to have it always at your left instead of holding the home button and swiping up, which is how I used to access it.
Wallpaper: Plain black.
Icons: I downloaded these *.png files from the net, and embedded them into the widget.
