The goal was to create icons with a blue neon glow. I designed all the icons from scratch myself, but because I suck at creating wallpapers, I had an image generator do it for me - the wallpaper is square, so it can also be used in vertical monitors.
I had fun creating some tweaks in the icons like the Vivaldi new version update icon being animated, for example.
NOTE: This is my first theme ever. So comments are very much appreciated!
