I have always detested the default LXDE theme, it does the job but just leaves me feeling a bit ill. This gives it a more pleasant flat color scheme, while also changing the default logo/wallpaper to something friendlier to the eye. Using:

• Color UI theme github (has some package requirements, but i didn't need it on lubuntu)
• Start menu icon link - (slightly modified from a personal experimental project by Jeroen van Eerden)
• Wallpaper link - (from wallpapercave.com )
