This is a simple wallpaper, consisting of white lines that vary in widths and opacity, simple radial gradients and a white, translucent "block" that covers half the screen. Everything else is completely transparent, meaning you can set the general colour of it yourself.
The screenshots show the default blue colour and a deep gold-ish background.
Feel free to rate and comment on what you think. I'm not a very impressive artist, but I would love to improve. Thanks in advance!
